Gymnastic body : static training

I will soon be able to train on front and back lever. Just need to finish the installations. and I will officially start a 8 week circuit (although I already started static training for a while now).
If all is good today I''ll be able to try my "max rep" for front and back lever in tuck position, I used to do it a little and my overall strength is better than it used to be for this kind of things, so I expect something like 15 /20 sec for max.
After that I'll introduce the "dynamic basic strength" training in the book. It's mainly upper body training which is good for me as it''s my weakness, and insanity works a lot on legs.
