So this isn't really a creation of a discussion....but more of a giving of thanks to Coach Sommer and his program. About two months ago, I obtained the GB book and lurked the forum on here.....and I started doing the WOD's two days a week in place of two CrossFit workouts a week (CF workouts 3 days a week still). Within this time, my 1 rep max for a weighted chin up went from 88lbs two months ago to 102lbs today! So thanks a ton!
