In June, we ran a combine and every player that had been lifting consistently showed huge improvements, 20%+ gains in their totals. We were also faster (40), more explosive (broad jump and shuttle) and the kids just carried themselves differently. We no longer looked like a young team, we looked like a Varsity team...Coaches told us we were the most physical team they played.
Now if you're a beginner and are working out without any guidance whatsoever, it's probably best to just stick with the basic program. One of the worst things a young lifter can do is take advice from other beginners on message boards – they usually have all the advice and none of the experience
