35 Min HIIT Workout With Weights

S1, E1: This fat burning HIIT routine focuses on the lower body to help lean out your legs, trim your thighs, and sculpt your butt. Each exercise will be 45 seconds with a rest period of 15 seconds in between. You’ll do 3 rounds of exercises with a different focus each time, but it’s all about the lower body here. You’ll start with a warm up to get your body ready, then finish off with a nice stretch to recharge and relax.
