The 100 push up challenge

[TheHeathens]

The push ups were all a little pointless really. Even after doing thousands my shoulders did not really change in the way they looked. At least the sits ups gave you visible abs (when done in conjuction with no pies) and helped with core stability which is useful for runners.
Anyone for a sit up challenge, I could get back into them.......................

Have a look on that site - there is a 200 sit-up challenge which I'm going to do after the push up one.

As for push-ups, the main increases in muscle should be across the chest, triceps and back rather than the shoulders. Doing military presses is probably the best way to get Herculean shoulders.
