Tutorial: Leg extension

Leg extension

Target: Quads, calves

Form tips:

• Sit up tall and keep your core engaged – slouching can aggravate your lower back, especially with heavier weights.
• Control your tempo and focus on the squeeze to get full benefit.

Modification – Dumbbell front squat:

• If the machine move strains your back, try a slow and controlled dumbbell front squat, focusing on engaging your core as much as possible.
