Knees over toes

Also called ATG · kneesovertoesguy · Patrick training · tibialis raises · ATG split squat

Community talk. May contain inaccuracies. Not medical, training, or diet advice. Sharp pain, fainting, or disordered-eating concerns need a clinician.

Knees-over-toes training explores strength with the knee traveling forward over the foot. It is closely associated with Ben Patrick's Athletic Truth Group (ATG), especially its deep split squat. People look it up to build movement confidence and mobility; the brand's pain-free performance claims are not guarantees.

01

What the movements involve

Knees passing the toes changes where the work goes. It is not automatically a form error. In a small barbell-squat experiment, preventing forward knee travel reduced knee loading but greatly increased hip loading. That finding does not establish a safe depth for an injured knee or test the ATG program.

Fry and colleagues · 2003

The split squat uses a deep staggered stance. One foot is forward and the other back as the front knee travels forward and the body lowers. ATG's young-athlete demonstration permits the front heel to lift; it is not a universal heel-down squat cue.

Athletic Truth Group · undated

A higher front-foot platform makes the range easier. Raising the whole front foot eases flexibility demands; hand support eases strength demands. ATG progresses toward lower platforms, less assistance and added weight. Range and load are separate adjustments.

Athletic Truth Group · undated

Tibialis raises work the front of the shin. The wall version keeps the heels planted while the forefoot lifts toward the shin. Moving closer to the wall makes it easier; standing farther away makes it harder.

Athletic Truth Group · undated

Backward work has equipment-free and sled versions. The beginner lifting article lists 200 yards unresisted, 100 yards with a sled, or two minutes on a resisted treadmill. It also allows this step to be omitted.

Athletic Truth Group · undated

Knee Ability Zero starts without weights. That book's starting format differs from ATG's loaded lifting programs. A free drill demonstration, the book and paid app programming are not interchangeable routines.

Athletic Truth Group · undated

One beginner lifting routine uses two weekly sessions. Each session appears at least once weekly. Its second session includes two tibialis sets up to 20 reps with a bar and four split-squat sets up to 12 per side, starting unloaded.

Athletic Truth Group · undated

02

Why people use it

The goal is strength through more available movement. Patrick presents the split squat as a way to practice squat mobility and strength one side at a time. This is his coaching rationale; a couch stretch alone trains a different task from moving against resistance.

Athletic Truth Group · undated

Strength training can also improve flexibility. A small trial found full-range hip/back lifting improved forward-reaching flexibility similarly to stretching, with greater strength gains. It studied 18 healthy young adults, not ATG split squats or knee rehabilitation. It supports the general idea, not promises of repaired knees or higher jumps.

BMC Sports Science, Medicine and Rehabilitation · 2024

03

Good to know

Deepest is not the same as best. ATG includes assisted and elevated versions. Advanced social-media depth is not a starting requirement, and creator anecdotes do not justify forcing painful positions.

Athletic Truth Group · undated

Locking, giving way or major swelling needs assessment. Severe pain, inability to bear weight, a badly swollen knee, or a hot/red knee with fever warrants urgent medical advice. Swelling after a session does not identify its cause. These drills cannot diagnose an injury or determine whether surgery is needed.

From community discussion

Short add-ons use two or three drills. Reports describe shin raises, split squats and sometimes step-downs in 10–20 minutes, two or three days weekly, before lifting or after easy cardio. These are people's adaptations, not the full ATG schedule.

Community

Reported rep ranges vary from the published routine. Examples include 15–25 slow shin raises and 8–15 split squats per side, bodyweight first. People describe changing range before weight, avoiding bouncing, and unfamiliar next-day shin soreness. Soreness alone does not show benefit.

Community

Easier stairs are one reason people keep a small routine. Some accounts describe less apprehension on stairs after about a month. Four-to-eight-week introductions sometimes become a ten-minute habit or stop altogether. Walking, a short written drill list, shoes that feel stable, and returning at shorter range after a layoff feature in these accounts.

Community

A full routine can take much longer than an add-on. An app subscriber struggled to fit ATG around 5/3/1 lifting and existing gym costs. Replies reported 20–25 minutes versus 45–60 minutes for book-based sessions. Those differences reflect users' versions and pace; adding another whole program also adds work and recovery demands.

Community · Reddit r/Kneesovertoes · 2024

One improvement story needed no sled. A lifter reported rebuilding squat/deadlift tolerance over three months, using partial Zero sessions three days weekly and ten-minute backward walks five days weekly. They noticed improvement after adding the walks but acknowledged coincidence was possible. Ordinary house/street walking avoided equipment hassle.

Community · Reddit r/Kneesovertoes · 2023

A first elevated hold still felt unstable. A beginner described shaking during a 30-second split-squat hold and next-day irritation. Replies emphasized more front-foot elevation and chair/rack support. Their guesses about spasms and sciatica were not diagnoses; an elevated setup alone had not made the attempt manageable.

Community · Reddit r/Kneesovertoes · 2025

Some keep other drills and drop the split squat. One poster continued twice-weekly KOT work but abandoned painful split squats. A commenter with prior meniscus/ACL surgery also described pressure and pain at depth. The discussion included other strengthening options: enjoying parts of ATG does not mean every movement helps every knee.

what People Say
  • The job: make the knee happy going forward so a squat or a step-down is not a fear. [community]
  • KneesOverToesGuy and ATG (Athletic Truth Group) are names associated with this approach in online training discussions. [community]
  • r/kneesovertoes and r/flexibility vs old “knees never past toes” school-PE. [community]
  • Why people stay: stairs and split squats feel less scary after a month. [community]
  • Physical therapists’ concern: copying a reel can mean forcing a painful end range without an individual assessment. [community]
  • Not a squat program. 5/3/1 still squats. This is extra knee capacity. [community]
  • Not couch stretch. Couch stretch is hip flexor. This is knee travel. [community]
  • “Bulletproof knees” is marketing language, not a guaranteed outcome from a set of drills. [community]
  • Pain during vs after: a little work-sore is common; sharp line-pain is a stop. [community]
  • Beginners do a short-range split squat to a pad, not a deficit ATG day one. [community]
  • It will not un-do a torn meniscus on a video. [community]
how People Run It
  • Common drill lists include 2–3 movements: tibialis raises, which lift the front of the foot to work the shin muscles; split squats; and sometimes step-downs. [community]
  • Slow. They own the bottom. [community]
  • 2–3 days a week as extra, often after easy cardio or before lifts. [community]
  • Front-foot elevation is a regression: the ATG explanation uses a higher front-foot platform to reduce the range demand. Lowering that platform makes the range challenge greater; added weight is a separate change. [community]
  • Heel and platform cues differ: ATG split-squat explanations can allow the front heel to rise. That is different from elevating the entire front foot on a platform. [community]
  • They stop a set when the knee line gets angry, not when the reel hits 10. [community]
  • Sled backwards if they have one and the knee likes it. [community]
amounts People Use
  • Tib raises: often 15–25 slow reps. [community]
  • Split squats: 8–15/side, bodyweight first. [community]
  • Frequency: 2–3 days / week. [community]
  • Session time: 10–20 minutes extra, not a 90-minute ATG religion. [community]
  • Progress: more range, then a little load — not both at once. [community]
how People Keep It
  • A short list on a note so it is not a 40-exercise app. [community]
  • They pair it with walking. [community]
  • They skip deficit work when the knee is already loud. [community]
  • Shoes they can feel the floor in. [community]
  • A PT or a coach if the knee already has a name (surgery, swelling). [community]
how It Feels
  • First tib workout: shins sore in a new way. Walks funny the next day. [community]
  • Split squat bottom: stretch and respect, or a pinch they should not push. [community]
  • After a few weeks: stairs feel less like a negotiation. [community]
  • Ego deficit: they limp and blame the method. [community]
  • Good day: knee tracks, heel stays, they forget the cue. [community]
  • Swelling after: they did too much range too fast. [community]
how Long People Run It
  • A 4–8 week introduction is how most logs start. [community]
  • Then it becomes a 10-minute extra or it dies. [community]
  • Not a 12-month paid program unless they want that. [community]
  • They return after a layoff at the short range. [community]
deep Dive
  • Couch stretch / 90/90 is hips. This is knees traveling. [community]
  • Ten-minute mobility can host tib raises without an ATG identity. [community]
  • First gym week should learn a squat that feels safe, not a deficit ATG. [community]
  • An exercise approach and a drug treatment are separate questions. The drill name does not supply a medicine plan. [community]
  • Sports-medicine nuance: some people report knee pain near the end of a movement's range. General discussion cannot diagnose an individual's knee pain. [community]
watch For Long
  • Sharp pain, locking, giving-way: a clinician, not a deeper split squat. [community]
  • Copying the full ATG program the first week. [community]
  • Bouncing out of the bottom. [community]
  • Treating it as surgery replacement. [community]
  • Loading a stretch they cannot control. [community]

      definition
      Knees-over-toes training is a label associated with exercises that allow forward knee travel, including the split squats, backward sled work and lower-leg exercises discussed around the ATG method.
      community Picture
      People compare individual drills, easier and harder variations, equipment needs and how this approach differs from the old cue to keep knees behind toes.

      guide
      what
      • The moving part is the knee traveling forward over the foot, in a range that stays controlled. Ben Patrick's Athletic Truth Group uses ATG for ass to grass, hips low enough to touch grass, and for the company name. Each piece is supposed to scale from easier to harder.
      • This is not the cue that knees stay behind the toes. Cleveland Clinic's January 16, 2026 article says keep the knees in line with the toes and the weight on the heels, and that deeper is reasonable without pain. TPI's ankle check treats the knee past the toes as available calf motion. Those pages are not ATG.
      • Patrick's beginner article uses backward walking or a sled, tibialis raises for the front of the shin, and the ATG split squat. His history page claims pain-free performance. That is his claim, not a result stated here, and the drills are not a surgery plan.
      how
      • Change one thing at a time. On the beginner lifting article, flexibility and load are separate on the split squat. A higher front foot makes the flexibility demand easier. The first set is bodyweight. Later sets may add a little load only when that first set is controlled, and the article says the first set stays bodyweight.
      • A concrete order from workout 2 on that page starts with backward work: 2 minutes on a resisted treadmill, 100 yards of sled, or 200 yards unresisted, when one of those is available and the knee tolerates it. Then tibialis raises, listed as 2 sets of up to 20 reps with a bar, or at least 20 reps at a wall. The wall version is heels away from the wall, back against it, toes lifting toward the shins.
      • The split squat on that list is 4 sets of up to 12 reps per side. Step into a long stance, lower under control, and stand without bouncing. If the bottom pinches, raise the front foot or take the load off. Do not buy depth and weight on the same step. Cleveland Clinic's basic-squat notes say the same thing about the bottom: do not bounce out of it.
      • The beginner article builds two different sessions and says each is meant to be done at least once a week. The knee-travel pieces can be the extra work inside a shorter practice. They do not have to become a six-day identity. Stop the set when the knee is angry, not when a rep target on a screen is still counting.
      understand
      • The ladder exists because stairs, kneeling, and a deep squat already ask the knee to go forward. The training version is a smaller dose of that position, then a little more. Patrick's pages also sell protected, pain-free knees. Read that as the claim on his site. The standard for a set is control, not a promise that the joint will feel a certain way.
      • Cleveland Clinic sports-medicine physician Matthew Kampert, DO, in the January 16, 2026 article, says deeper squatting can be reasonable as strength and mobility improve if there is no pain, and that sharp or sudden pain is the point to consult a clinician, a physical therapist, or an athletic trainer. Fainting or chest pain is the same stop. His basic squat still keeps the weight on the heels. ATG's split-squat regression uses a higher front foot instead. Those are different setups.
      • The common miss is copying a full ATG week onto an irritable knee, or adding range and load together. The beginner article itself asks for more patience once weight is involved. This is the wrong tool as a substitute for an assessment after an acute injury, and it is not the squat program on a barbell day. Reports of stairs or split squats feeling different stay in the community notes.
