I made the mistake of telling the gym trainer guru, Hans Hoeller, that I had dropped my leg press weights down to 130 pounds. He asked me how much I weigh and I told him 165 pounds. He then told me that my legs probably weigh 10 pounds each, below the knee,
which left 125 pounds for me to lift my body off a toilet. I got the message. I am now doing 150 pound leg press with 10 reps followed by 190 pound leg press with 10 reps and finishing with 200 pound leg press weights with 10 reps. Because I am working to improve my fast twitch muscles, I wait about 1 to 2 minutes between sets. I had no clue that there were fast and slow twitch muscle fibers until I learned this from Hans.
