I'm new to parkour and most sports in general, I played soccer from age five to eighth grade, then stopped in all sports and became terribly out of shape until about a year ago when i started to work out and run. I still have weight to lose and muscle and endurance to gain so I'm starting this so I can keep track of my progress and hopefully get some helpful advice, although just from reading all the different threads around here I have gained a huge wealth of knowledge!
I have a usual routine for working out which is usually:
jumping jacks or jumping in place with sets of 50..100..150..150..100..50 with either sit ups or lifting weights in between but i've decided to switch routines since i've been doing that one for awhile now. can anyone tell me if that is an ok workout or if i'm just wasting my time with jumping jacks and sit ups?

Alright so here goes...
Monday 01/28/08APK warm up:
3x10 push ups
3x25 squats
5 samson stretches (each side)
i don't have a pull-up bar so i skipped this, although i went to a park to attempt it and couldn't even do one lol, any advice on working the muscles that you use to do a pull up?
Tuesday 01/29/08APK warm up:
3x10 push ups
3x25 squats
5 samson stretches (each side)
frog stand for 60 seconds, it took me awhile but I finally reached 60 seconds, using this to build up to a planche
Wednesday 01/30/08APK warm up:

about 5 minutes of QM, this was mostly a first time doing this to see how it was, more difficult than i thought.
