My idea would be to increase your weight in the pull ups via a weighted belt. Work on a huge max! Why? Percentages. If I can bench 365 and you can bench 500 who is going to lift 225 more times? Me or you. You. The reason…225 is 45% of your max and more than 60% of my max. For you 225 is easy.
Say you weigh 200 lbs and you can do one pullup with 200 lbs attached you are doubling your weight. Now when you do un-weighted pullups you are doing less than 50% of your max.
I have not done any high rep exercises for quite some time. I have been training raw for quite a few years and my bench has sucked. I started training West Side a few months ago. I got my bench up to 365…don’t laugh hey man quit rolling on the ground compose yourself. Ok now that your done laughing, I’ll continue. A few months ago it was all I could do to finish a bench workout of 4X3 with 225. Two weeks ago I decided to try 225 for a rep max. I got 14 without a spotter. Two more than all the reps involved in a multiple set workout a few months ago.
