If you’re tired of doing regular old push ups, try raising the bar
on this classic bodyweight exercise by incorporating a BOSU trainer.
If you dont have a BOSU at your gym you can pick one up at your local
sporting good sore. They run about $100, but they last forever.
(Ive had a few of mine for almost 10 years now).  Here’s the rule of
thumb to go by: The further away your leg and foot goes from your body,
the more challenging the push up becomes. You’ll see… Beginning
and advanced progressions are demonstrated.
