Full Body HIIT

Instructions
Find a space that is clear in front, behind, and to each side of you to avoid injury. Perform a warm-up that consists of an activity that gradually increases your heart rate and moves your joints through a moderate to large range of motion such as the one below. Perform each exercise in the warm-up for 45 seconds.

It is encouraged that you modify each exercise to a version that is best for you.

Workout
Repeat each circuit 3 times. For round one and two, perform the exercises in the circuit for 40 seconds and then rest 20 seconds. Each exercise should be performed at 70-80% intensity. For round three, perform the exercises for 30 seconds and rest 30 seconds. Exercises should be performed ALL OUT at 90-100% intensity by increasing speed and power through each movement. After completing Circuit 1, rest or jog for 90 seconds and then move to Circuit 2.

Equipment Needed: You will need a stopwatch or timer. Mat suggested. Make sure you have plenty of open space to perform all exercises.
