I am without any equipment for a few weeks, so I will only be doing situps and pushups to maintain and maybe get a little stronger.
1. Where can I find some good-quality animations of exercises, I know you guys have some here, but you only have a few that are actually animated...
2. With push-ups and sit-ups what would be some good rep scheme ideas? Here's what I was thinking of, maybe someone has a better idea;
Pushups - 5 sets to failure
Situps - 5 sets to failure
3. I was thinking of doing 5 sets of pushups and 5 sets of situps every day. Is this good? Or is it overtraining?
4. I am having trouble keeping my back straight and firm when doing pushups. I can keep it straight for the first few reps, then my lower back starts to sag. How can I strengthen my lower back and get perfect form on my pushups?
