Heels Up at Half Depth
A 29-year-old man with two years of lifting experience asks you to coach his squat. He has no pain and no injury history. In his bodyweight overhead squat, his heels lift about 2 inches off the floor at roughly half depth, his torso pitches forward, and his arms drift forward. His knees track over his toes and do not collapse inward. In a half-kneeling ankle test, both ankles fall about 2 inches short of the wall. He wants to squat below parallel with a barbell and also wants to deadlift heavy. He trains three days per week and has no equipment restrictions.
1. What is the most likely limiting factor, and what do the heel rise and forward torso tell you mechanically?
Read the worked answer
Most likely limiter: ankle dorsiflexion. The half-kneeling test is the strongest single piece of evidence - roughly 2 inches short of the wall bilaterally suggests both ankles are restricted, and the deficit is symmetrical, which is consistent with a chronic mobility limitation rather than an acute injury.
The mechanics of the compensation: with limited dorsiflexion the shank cannot translate forward over the foot, so the center of mass cannot stay over the base of support in a normal squat. The system solves this two ways:
- Heel rise effectively adds dorsiflexion by tipping the whole foot onto the forefoot - it converts the squat into a calf raise.
- Forward torso pitch shifts mass forward to counterbalance the hips traveling back, and the arms drift forward for the same reason.
What the clean knee tracking tells you: it argues against a primary hip-control or glute-medius problem. When valgus and knee collapse are absent, the knee is doing its job and the restriction is upstream.
Caveat before you commit: this is an overhead squat, so a thoracic extension or shoulder limitation could also drive the forward drift and arm drop. Confirm with a goblet or front-rack squat and a heel-elevated squat. If a 1-inch heel lift restores depth and an upright torso, the ankle is the driver.
2. You have eight weeks. What do you do with his squat, and what do you do with his deadlift in the meantime?
Read the worked answer
Squat:
- Weeks 1–4: heel-elevated (1–2 inch plate or a squat shoe) goblet or box squat to full depth, 3–4 sets of 6–8, tempo 3 seconds down, 1 second pause, controlled up. The elevation lets him train the pattern through range while the ankle catches up.
- Daily ankle work: bent-knee (soleus-biased) wall stretch and a straight-knee (gastrocnemius) variant, 2–3 x 30–45 s each, plus loaded dorsiflexion drills such as a knee-to-wall or a barbell-weighted ankle rock. Consistency beats duration here.
- Re-test at week 4. If range improves, remove the elevation progressively - heel lift first, then depth - rather than jumping straight to a full barbell back squat.
Deadlift:
- Keep loading it, and load it hard. The deadlift is a hip-dominant hinge with a near-vertical shin, so it demands very little dorsiflexion. It is the lift that lets him train heavy while the ankle is addressed.
- Trap-bar and Romanian deadlift are useful variations depending on his leverages and goals.
What not to do: do not load a barbell back squat through a pattern that pitches him forward and lifts his heels. He would be training a compensation under load, and the position of his spine and knees at the bottom is not one you want to reinforce with weight on his back.
3. Three weeks later he reports sharp pain at the front of one knee "only at the bottom." How does that change your read and your plan?
Read the worked answer
Change the plan immediately; do not change the diagnosis. Sharp anterior knee pain at end range is a reason to stop loading that range today, not a reason to name a pathology. You cannot diagnose patellofemoral pain, a meniscal issue, or anything else from a description.
In the session:
- Cut depth to his pain-free range and reduce load.
- Swap barbell/box squats for pain-free options: box squats to a pain-free height, hip-dominant work, isometric wall sits or Spanish squats if those are comfortable, and quad and hip strengthening through ranges that do not hurt.
- Re-test the ankle and re-check his foot position, stance width, and whether he has been doing the mobility work.
Referral triggers: pain that persists beyond two weeks of modification, pain at rest or at night, swelling, giving way, or pain that worsens as the session goes on. Send him for evaluation rather than working around it indefinitely.
Also re-open the original read. Limited dorsiflexion changes how load is distributed up the chain; knee symptoms appearing at the bottom of a squat is consistent with the ankle still being the upstream problem, and it is worth re-measuring whether his range has actually changed rather than assuming it has. If progress has stalled, that is the finding, and it belongs in the referral conversation.
