Start with feet slightly wider than hip distance apart. With feet parallel to each other, slowly start to sink into your heels, like you're going to sit in an imaginary chair.
Hover at the bottom of the squat for a few seconds before pressing evenly into both heels and slowly standing back up.
When you come to the top of the squat, keep your left leg straight and transfer all your weight into your right glute. Slowly lower into a side lunge on your right leg. Your left leg should stay straight with pointed toes, with minimal weight on it.
Add a couple of pulses at the bottom of the lunge before your slowly stand back up.
Perform another squat and then go into a side lunge for the left leg.
Repeat on both legs 10 times each for one complete circuit. Perform the circuit twice.
