30 Minute Total Body Workout

Perform 60 seconds of squat jumps.  If you cannot handle the impact substitute regular squats.
Move right into 60 seconds of pushups keeping your hands wider than your shoulders.
Next, use a heavy resistance band to perform a minute of squats into low rows.
Move on to 60 seconds of plank ups.  Add a regular pushup to the up position each time for an extra challenge.
Following your plank ups, complete 60 seconds of bench dips for your triceps.  Try keeping your legs straight during this exercise.  If you reach fatigue before the end of your minute, try to continue the dips with bent knees.
Standing with both feet on a moderate resistance band or one foot on a heavy resistance band, move right into a minute of curls.  The key to this exercise is control.  Make sure you’re not letting the band snap back down too quickly.  Keep a nice, steady motion throughout the entire set.
Spike your heart rate with a minute of burpees.  This is the fun part!
Finish up with a minute of bicycle crunches making sure to straighten your opposite leg completely out with each repetition.
Take a two minute rest and repeat the circuit two more times.
