How Not Resting Properly Could Affect Your Muscle Gains
Jack finishes a focused set of exercises and re-racks the weight. His legs are wobbly, he feels light headed and he takes a big swig from his water bottle. He looks down at his watch and presses the start button to begin counting down backwards from 2 minutes.
He saw on TV that 2 minutes is the perfect rest time between sets, and what he wants is to do it exactly in that way. So, the watch beeps and he's be back in the squat rack ready for his next set of exercises with the weights.
Time is up. His still feel weak and his heart is still beating a lot, he doesn't feel completely ok, but the watch beeped and that means his has to go back and perform another set, it does'nt matter how he feels.
He unracks the weight and squats down. His legs still burn and he wishes that he could have had more time to prepare for this set. He puts forth a mediocre effort, re-racks the bar, and sets his watch for another 2 minutes. Bobby, just like a ton of other aspiring lifters in the gym, is making a deadly, critical mistake.
The only thing he is doing is to force his body to train at an effort level really far for his maximum potential, and his muscles are rarely being stimulated to grow.
Muscles grow because of an adaptive response to stress. You lift X amount of weight for Y number of reps, and your body adapts to this level of stress. In order to see continual gains in muscle size, you must continually force X and Y to higher and higher levels.
It's quite simple: it's about lifting as much weight for the greatest number of reps that you possibly can. And repeat, and repeat, and repeat...
If you don't rest enough between sets, you will not reach your maximum strenght potential sacrificing the amount of weight you can lift, and also sacrificing the amount of muscle you can build. So, to begin the next set qhen you are still tired is the big mistake you should not make.
So, return to your exercise set when you feel you are again at 100% of your strenght capacity. When will it be? When your body tell you so, listen to it an you will know when it is time to the next set.
A deadlift and a tricep pressdown aren't exactly in the same boat here. After a heavy set of deadlifts to failure I'll usually be resting for at least 5 minutes, often even more. A set of tricep pressdowns is obviously not as taxing and may only require a rest period of 2.5 minutes for me to feel fully recovered.
