Deanie,
If you want more challenging push-ups, try doing them with your hands on a med ball (or one hand on a med ball, if both is TOO challenging).
You could also elevate your feet to add intensity, pr raise one leg in the air as you do the push-ups.
Be careful about increasing range of motion if you use push-up bars, as it can put too much stress on the shoulder joint.
Yikes!Kathryn,
I don't think you noticed that Deanie's post is 2-1/2 years old. So, is the last response before this thread got revived.
