1. CLOCK LUNGE MATRIX

Beginner: 5 reps each leg

Intermediate: 5 reps each leg, holding a pair of dumbbells by your sides

Advanced: 5 reps each leg, holding a pair of kettlebells overhead

Stand on one foot and imagine you’re in the middle of a clock face.

Place your non-standing foot at 12 o’clock in front of you, then pivot and place it at 6 o’clock, then 3 o’clock and 9 o’clock. That completes 1 rep.

On the first rep, this movement should be a step, but increase the range with every rep until you reach a lunge. Then switch legs.
