My legs are burning! I did sumo squats, jump squats, and lunges. I’m beat .

What’s your favorite HIIT exercises. I tried sprinting on the treadmill today for 10 rounds. 15 sec sprint 45 min rest. 1. It was hard cause you had to press buttons to change speed 2. My shins cramped so bad I could only get though 5 3. I switched to battle ropes and did 10 cycles there

Newly pregnant, and don’t want to gain a ton of weight here. Keep a healthy body:)
