Should i start here with f2?
Which one should I do or wait for foundation 3?
I can do an L sit for maybe 10 seconds on my finger tips. I can tuck my knees in and lean back on a chin up bar. I can do a few one arm push ups (legs apart though). 10 straight bar dips, 20 hanging leg raises (not v raises), a few assisted one arm chin ups ups and four to five chin ups with 45 lbs attched (i am 5'1" and 121 lbs.), quite a few at least half way down if not farther single leg squats, 7 full range handstand push ups against a wall and just start barely on a planch with my legs up and knees tucked in.
I hope that gives you some help on where I should start.
