Below you will find many workouts that can be modified to fit your fitness level. You can do more rounds, less rounds. You can do more reps, or less reps. You can add weights (kettle bells or dumbbells) or use just your own body weight.
If you are a beginner…take your time and concentrate on the movements rather than your speed. As you develop your form, you can pick up the intensity.
For those of you beyond the beginner stage….what you put into the workout is what you will get out of it. Remember HIIT is highly effect in fat burning and muscle building….and if done right, you can continue to burn calories even hours after your workout.
