Iron Mind (www.ironmind.com) has a book on the 20 rep squat program. It claims you can gain 30 pounds in 6 weeks.
I first used the program in 1993. I went from 155# to 180# in 6 weeks. It is a brutally hard program if done correctly.
Some things I would suggest:
Have some one count the reps for you and out loud. When you get to rep 15, you will forget where you are because of load and all of breathing you are doing.
Eat! You cannot grow if you are not eating to support the growth!
You need a spotter. Even if you are in a power cage you need some one telling you to keep going. The killer for me was rep 17, every time. When I got to rep 17 I could talk myself out of the last three reps everytime unless I was being yelled at. It really helps if someone is “ordering” you to continue.
EAT!!
It don’t count if you don’t do 20 reps. Suck it up and do them all. It is a great motivator to walk (crawl) out of the gym knowing you did all of the reps.
EAT!
I did one set of 10 with an empty bar to warm up. Then get on to the weight for the day. The goal is to get the reps and add weight next work out.
When the weight starts to get up there (for me the 300# range) You might want to add just 2.5# each work out. The goal: add weight, do 20 reps.
EAT!!!
If you feel like doing anything else after the 20 rep squat and pullovers, you need to be thinking about adding more weight. I would squat once every 5 to 7 days and walking would be tough for several days after each squat session.
Eat!
The 20 rep squat program was one of the most effective programs I ever used. I made the best gains in the shortest time frame.
EAT! Remember, you want to grow muscle!
It is hard work.
It was worth it to me.
If you try it, give it 100% and I think you will be pleased with the results.
Your results may vary but I have never heard of anyone who gave it 100% that did not make impressive gains.
Good luck and let us know how you do!
