Not Cathe here, but in a recent post she recommended negative pushups. This is a cut and paste of what she wrote:
"Hi JuliaBelle! I have to tell you that 8 push ups on your toes is GREAT!!! It really is. That is more than what I typically see in many classes.
I see that you have already gotten advice so let me just add that you can also try doing "negative push ups" to improve your strength. To do this start at the top of your push up position (straight leg up on toes) and lower your body down very slowly (for about 10 seconds down). When you reach the bottom, allow your body to make contact with the floor for a second and then assist yourself back up for another slow descending push up. Note than when you prop yourself back up to the starting position, you are assisting it with bent knees (or however is comfortable) but you are NOT pushing yourself back up the way you typically would.
Working a movement like this, on the negative phase of the contraction, helps to improve strength.
Try doing 2 sets of as many reps as you can like this three times a week. On JUST ONE of those three days, do two sets in the morning and then repeat it again at night. Within three weeks you should see nice improvements.
Good Luck! "
Hope this helps (sorry I don't know how to post a link, so cut and paste was the best I could offer).
