I remember hearing that the fastest muscles to tone are your arms, and have heard that actresses do push-ups before wearing their Academy Awards gowns
I have also heard my Marine husband say that push-ups and sit-ups are two of the most complete exercises and that you don't need a whole bunch of fancy ones.
I recently heard my massage therapist recommending push-ups to a client to strengthen her core and her back.
I have learned in my workout class that push-ups and planks strengthen your abs.
So Mother Rabbit encourages a push-up regimen. Start small and build up. Form is everything. Arms shoulder distance apart. Head straight. Abs in tight. Try it everyday for a month. Start with 20 per day. (And let's not do sissy girl-push-ups.) You can do it.
