helo all. do u consider yourself a fitness freak or something like that? im a fitness freak myself. i work out regularly. and just now i gave a try to something called "feats of strength". just push myself to the limit. in both muscular strength and muscular endurance. this is what i did just now, i weight 170lbs/77kg and i did 12 pushups in a row with a 120lbs/55kg person standing on my shoulder blades. all the way down all the way up. 12 pushups in a row with 120lbs standing on my back,. and then i rest and take a breath for less than 30 seconds and continue with 35 diamond pushups in a row. no more 120lbs on my back. just my bodyweight for 35 diamond pushups in a row. honestly, what do u think of my feats of strength for a guy who weights 170lbs/77kg and stands at 5'11/180cm. thanks and have a nice day.
