Granted, Randy is 45 years old... but I'm not sure it would matter how young or old anyone is who steps into the cage with Brock. He is the epitomy of unstoppable power and strength.
If you ever saw pics or video of Brock's high school matches, you know that although he was a muscular and strong looking kid, he didn't have nearly the muscle mass that he does now.
So... how do you go about packing on functional muscle mass for wrestling?
If you're in high school, you need to train as a 'hard gainer.' That means your strength and mass workouts should be abbreviated, and your total training time should be no more than 2 hours per week!
Here's a sample 'hard gainer' mass program for wrestlers:
Trap Bar Deadlift - 1x20 with rest pause (8-10 reps to failure... rest 15 seconds... as many reps as possible... 15 more seconds of rest... as many reps as possible... etc.. until you reach 20)
Shoulder Width Grip Incline Barbell Press - 2x5
Reverse Grip Chinups - 2x6
Plank- 2x as long as possible
Barbell Squat - 1x20 with rest pause (see above)
Standing Barbell Shoulder Press - 2x5
Reverse Grip Barbell Row - 2x6
Twisting Crunches - 2x as many as possible
* Take 2-3 days between workouts
This type of training is guaranteed to pack on 'Brock Lesnar' type strength and mass to any wrestler... but you must consume enough calories from protein, carbohydrates and fats.
To figure out how many calories you should eat to pack on muscle, simply take your bodyweight and add a zero. Now double it! That's how many calories you'll need as a high school wrestler if you have trouble packing on muscle.
Example: Your bodyweight is 150. If you add a zero you get 1500. If you double it you get 3000 calories daily.
Brock Lesnar follows a very intense training regimen... with a lot of bodybuilding-type training. When you are in your upper 20's you can pack on mass with his type of program. But if your body is still growing you need abbreviated mass and strength training to be successful.
