“Along with the full-body flexion, it’s a very advanced single-leg squat variation,” says PT Andy Vincent. The full-body flexion means you’re using every muscle to stand up. Plus, by working on one leg, you engage all the smaller stabiliser muscles, as well as the large ones in your legs.
the large ones in your legs. You have to go slow, too. Vincent warns against blasting through reps. Instead, focus on a full range of motion and time under tension. Work up to three sets of six reps on each side to kickstart your progress and let the good times roll.
1. GET SET
Lying on your back with one leg off the floor, position the heel of your other leg close to your glutes and keep it flat on the ground. Hold a weight plate behind your head for counterbalance.
2. CRUNCH TIME
Take a deep breath, then work your core. With your arms held out straight, perform a rapid crunch, rolling your shoulder blades and mid-back off the floor fast. Keep that foot up.
3. BALANCING ACT
Hold your arms in front of you as your weight transfers to your foot. Ensure the load stays evenly distributed from your heel to your toe, and the centre of your knee stays in line with the middle of your foot.
4. STAND TALL
For your parting shot, drive through the floor to bring your body up and stand. As you reach the top, squeeze your glutes to finish the move with your hips. Now, slowly sit back into the squat and roll down under control. Reload, and go again.
