How to do it well

The set-up and the rep in full, then the cues the app shows on the exercise card — the short version, for the moment you are standing in front of the bar.

Set-up

Set the rack so the bar sits at mid-chest height. Step under it and rest it on the upper traps, below the bony point at the base of the neck, hands as close as the shoulders comfortably allow. Squeeze the shoulder blades together to make a shelf, stand it up, and take two or three steps back. Feet about shoulder width, toes out 15–30°.

The rep

Breathe into the belly and brace around it as if you were about to be hit. Break at the hips and knees together and sit down between the feet, knees travelling out over the toes. Reach the depth where the hips are level with or below the knees without the lower back tucking under, then push the floor away through the whole foot and stand tall.

Common mistakes

What goes wrong, and the fix

What goes wrongThe fix
The hips shoot up first out of the bottomThe chest and hips should rise at the same speed. The load is usually too heavy for the quads — take weight off and pause at the bottom.
The knees cave inwardPush the knees out in line with the toes on the way up. If it persists at lighter loads, add single-leg work.
Losing the brace halfway through a setBreathe and brace before every rep, not once at the start of the set.
Scaling

Make it easier, or harder

Easier
Box squat to a set depth, or a goblet squat.
Harder
Tempo — three seconds down and a one-second pause — before chasing more load.

How Train Smart prescribes it

The sets and reps below are the authored starting point. The actual weight you see is calculated from your own last top set and the week you are in within your four-week block.

In the collision codes this is the base strength lift: more force into the ground at contact, and a stronger platform for every other lower-body quality. It is heaviest in the max-strength blocks and carried at lower volume once the season starts.

If you cannot do this one

Rack taken, kit missing, or it does not suit you. These are the swaps the app offers, matched by movement pattern and body region — each with the reason it is a fair substitute.

AlternativeWhy it works as a swap
Front SquatMore upright — quad + core emphasis, great for cleans/sprinters
Goblet SquatEasy to load, joint-friendly, great depth
Box SquatControls depth, easier on the knees, builds drive out of the hole
Tempo Front Squat3s down — quad eccentric for jumpers + sprinters
Safety-Bar SquatBar across the chest — shoulder-friendly, brutal for the upper back, great for contact athletes
Zercher SquatBar in the elbow crooks — anti-rotation trunk + drive for rugby/MMA
