New HIIT Circuit!! Grab your jump rope and a sandbag! If you don't have a sandbag, you can try and create one yourself by using several different methods such as this one! You will complete each exercise for 50 seconds with 10 seconds rest between exercises. I go through the routine once with you below, and you can hit replay to run through it 1-2 more times. For beginners, shoot for 1-2 times total, intermediate 2-3x and advanced 3+. One round will take you 10 minutes. If you want to go for 3x through, you will program you timers for 30 rounds. Take a break when needed and challenge yourself with the weight you use. The sandbag I used in this routine weighs about 25 pounds. If you don't have a rope, complete high knees for the 50 seconds.
