I was told today that flat legged sit-ups are bad for your hips, true?
Flat legged sit-ups- you lay flat on your back, arms to sides, legs together and straight. One rep consists of you coming up and getting your chin as close to your thighs as possible, then back down.
Is this bad for your hips or any other part of your body?
Also, this summer I am going to be camping/moving. I'm not sure how long I'll be doing that, depends on how long it takes to find a place to live. I'm going to obviously have to stop lifting, but I want am going to keep doing calisthenics, running, and I am going to bring some dumb bells so I can do some exercises with weights.
My question, since I won't be lifting, would it be wise to do pull-ups, push-ups, sit-ups, dips, squat thrusts, toe raises, and the exercises I'll do with the dumb bells everyday? Those exercises with dumb bells will be shoulder complex, forearms, tricepes, and military press.
Or should I have the same attitude as lifting, don't lift the same muscle everyday, no more than every other day? I will do the same thing I've been doing for running, long distance MWF, and sprints Tues/Thurs/Sat.
Thanks for any and all help.
