When you do any exercise routine, it can be tempting to start compensating with your
back. Avoid this at all costs! Try to remember the muscles that you are targeting in
each exercise and AVOID relying on your back when it is not supposed to be used.
No matter how careful you are, your back will probably feel some tightness from the
running and the whole body routine. Stretch it out as you are nearing the end of the
exercises.
