The day I tried this I had one of the best workouts I've ever head. I suggest everyone who's an experienced lifter to try it!
This Quote by Arnold Schwarzenegger is from 1975
"I finally arrived at the idea of shocking the muscles. So once a week I took a training partner and drove out into the country with the weights. We limited ourselves to one exercise for a particular body part. I remember for the first day we carried 250 pounds into the forest and did squats for two hours straight.
I began by doing 20 repetitions with 250 pounds; then my partner did whatever he could. Then it was my turn again. We ended up doing something like 55 sets of squats each. The last hour seemed endless.
But it worked. Our thighs pumped up like balloons. That first day we gave our thigh muscles such a shock that we couldn't walk right for a week and each of us put something like an eighth or a quarter of an inch on our thighs; they just blew up.
They had no chance to survive except to grow. We made it a regular thing. We brought girls out there to cook. We made a fire outdoors and turned the whole thing into a little contest. We worked hard, but we had a good time.
After the muscle-shocking sessions, we drank wine and beer and got drunk and carried on like the old-time weightlifters sometimes it be came pure insanity."
It's definately not for someone who hasn't been lifting for more than a year or two because you definately have to know your body and how much stress your joints can take.
