Zercher Squat: the front-loaded squat for legs and core
The zercher squat is a barbell squat with the bar held in the crooks of the elbows, which forces an upright torso and hammers the quads, core, and upper back. It looks awkward and feels brutal — and that's the point.
How to do the zercher squat
- Set the bar in a rack around belly-button height (or deadlift it up and rest it on your thighs to get into position).
- Hook your arms under the bar so it sits in the crooks of your elbows; bring your forearms up and brace it against your body.
- Stand with your feet shoulder-width, brace your core hard, and unrack.
- Keeping your torso upright, push your hips back and squat down until your elbows touch your knees/quads.
- Drive up through your heels to stand.
Push off your heels to keep the bar over your midfoot.
Sets and reps
Train it for volume and quality, not a one-rep max — the bracing fails before the legs do. Rest 45–90 seconds.
| Goal | Sets | Reps |
|---|---|---|
| Strength | 3–4 | 5–8 |
| Hypertrophy | 4–5 | 8–12 |
| Endurance | 2–3 | 12–15 |
Muscles worked
Primary — the quadriceps, glutes, and adductors.
Secondary — the abs, obliques, spinal erectors, upper back, and biceps all work isometrically to hold the bar and keep you upright.
Common mistakes
- Letting the upper back round or tilt forward — push off the heels and stay tall.
- Too much weight — the elbows and bracing fail first; build up slowly.
- Not bracing the core — the whole lift depends on it.
- Setting the rack too low — it makes unracking hard when you're fatigued.
Variations and alternatives
- Zercher carry and zercher split squat — same front-loaded demand, different patterns.
- Kettlebell or sandbag zercher — easier on the arms to start.
- The front squat is a similar front-loaded option with the bar on the shoulders.
For more machine-based quad work, see the hack squat and pendulum squat, or slot it onto the leg day of a split like PPL or PHUL.
Common questions
What muscles does the zercher squat work?
Mainly the quads, glutes, and adductors, with the core and upper back working hard to keep you upright.
Is the zercher squat better than the back squat?
It's not a replacement — it's a great accessory. It loads less weight but builds core and upright-torso strength and is easier on the shoulders and wrists.
Does the zercher squat hurt your arms?
The bar pressing into the crooks of the elbows is uncomfortable at first; a towel or sleeve helps, and you get used to it in a few sessions.
Do I need a rack for zercher squats?
No — you can deadlift the bar up, rest it on your thighs, and slide your arms under to get into position.
