Day 15 is Calyn's full body HIIT and strength class. Strength and cardio share the session. You need a bench or a sturdy chair.

It kicks off with a mobility warm-up. From there, the first circuit runs twice. Think jumping jacks, squat swings, and bench hops. Then ankle weights and a band go on for the second circuit, also twice through. It works the glutes, outer thighs, and triceps on the bench. It finishes with a HIIT round and a calf stretch.

Equipment: bench, 8 lb or 10 lb dumbbells, resistance band, ankle weights
Beginner: 5 lb
Intermediate: 8 lb
Advanced: 10 lb
