the good form chin up definintion needs to be corrected. pull-ups have palms facing out and chin-ups have palms facing the body. the graphic showing a chin-up is also weak and confusing. I entered 14 in inital test value and it starts me out doing 2 chin-ups and then 2 more after resting a minute. I then entered 20 for the inital test and it doent change the work regimen. not really a program at all.
