I been reading around the way i use to do cardio was 45min pretty fast jog on the bike eliptical and mill
but now i am researching and thinking of going 15-30 MIN reaL HIGH INTENSITY
so today 4 the first day i went to the track sprinted the straight aways walked the turns for 20min and wow............i was hurting
i am reading and the purpose of this is to speed up metabolism by increasing intensity with a slow break and then bringing the intensity back up.......
instead of 7 days a week ill do three till i hit a peak then ill up
why i am here chris acetos champioship BB anybody ever read sick book
