Workouts - Hundreds (100s)
The name kind of says it all - do a hundred reps of each exercise. This is a killer. I have friends - including some former NFL guys, who live by this routine.
Take a weight that you can do a set of 15 to 20 reps with. Go.
Some people do sets of 20 or sets of 10 with little rest between sets.
You can also just do as many as you can. Short rest. As many as you can. SHort rest As many as you can. Keep that up until you get to 100. You might be doing 1 or 2 at a time by the end. You will feel it and should get great results.
This is good with dumbbells or machines. Not sure it is safe with something like a bench press or squat as you are going to get very fatigued and that could be dangerous.
