Setup
- Set the Smith machine bar to roughly mid-chest height.
- Place the bar in the crook of your elbows, keeping your forearms tucked close to your chest with hands clasped or fists pointing up.
- Position your feet shoulder-width apart, slightly in front of the bar to allow for a vertical torso.
- Brace your core and rotate the bar to unhook it from the safety pegs.
How to do it
- Inhale and lower your hips back and down, keeping your torso upright and elbows tucked tight against your ribs.
- Descend until your thighs are at least parallel to the floor, ensuring your knees track in line with your toes.
- Exhale and drive through your mid-foot to return to the starting position, maintaining a proud chest throughout.
- Maintain a controlled tempo, taking 2-3 seconds for the descent and 1-2 seconds for the ascent.
Form checklist
- Keep your elbows high and tucked to prevent the bar from pulling your torso forward.
- Maintain a neutral spine and avoid rounding your upper back under the load.
- Keep your heels firmly planted on the floor throughout the entire movement.
- Ensure your knees do not cave inward during the drive upward.
Pro tips
- Use a bar pad or wrap a towel around the bar to protect your inner elbows and increase comfort.
- Focus on 'scooping' the bar upward with your arms to engage the upper back and stabilize the weight.
- Actively pull your belly button toward your spine to maximize the anti-flexion core benefits of the Zercher position.
Make it harder
- Incorporate a 3-second pause at the bottom of each rep to eliminate momentum and increase time under tension.
- Perform 1.5 reps by descending fully, rising halfway, descending again, and then standing up completely.
