There's a Surya A between every pose in the seated and closing sequence. It's 60 pushups in addition to the additional strain on the body from the other poses. The Ashtanga ideal is that you'll do this entire sequence 5-6 times per week. seems like a repetitive motion, eh?
it works for some people. for me, i had a rotating list of maladies, from wrist and elbow problems to an attractive buildup of fluid behind my knees. i would back off the affected area, but i never slowed down as much as i could have.
eventually, the short term wear and tear of this practice, combined with 10 years of doing similar practices, eventually just wore my poor rotator cuff out. i'm guessing here, but i think the bicep tear came from compensation for the rotator cuff.
and that's more than anyone needs to know about my maladies.
