For squats...

Could i fill a back back with weights and do squats and lunges etc is this ok? or could it cause injury?

Giving you the benefit ov the doubt you're not a troll here: But your posts make zero sense. If you want help then explain things a bit better.

While im camping for a week i wont have the use of a gym.. was thinking i might just fill my back pack up with some sand bags to do some leg workouts. Bad idea or good idea?

Your so paranoid about troll shit that your being one yourself. It was a pretty simple question.

Peace

My 2c worth - I wouldn't use a back-pack as a back-pack, you'd probably find it hard to keep the curve in your back. But if you sat it crossways like a power-bag, then maybe. Use it for front squats, lunges maybe.

Or you could try sissy squats. No weight required but still very effective. YouTube them if you're not too sure what they are
