When you start to approach failure, your body releases hormones and builds more sarcoplasm in the muscle cell. It does this to allow itself to keep going even when you think you cant. getting those last reps are the most important part of the exercise. Whatever challenges your body the most is most likely causing the most progress as well.  Not only does intensity affect muscle growth but volume does as well. Think of it like this. If you curl 30 lbs 10 times youve curled 300 lbs in total overtime. add 5 lbs and you can only get 7 reps. the total weight was 245 lbs instead of 300. Turns out it was probably a little easier to stop at 7 reps instead of 10 depending on how long the reps take. In some cases it’s better to hold the weight at the extended portion of the exercise where the most of the “stretch” occurs. This allows for better control in every position, more and constant muscle stimulation, and increases mechanical overload. The Mechanical tension an exercise has is important for bodybuilders to increase difficulty without increasing the weight. 

When it comes to building muscle, finding the right training split is crucial. Welcome to a revolutionary approach designed to maximize your gains and enhance your recovery like never before: The Optimized Muscle Group Split. This split focuses on hitting one muscle group per day with increased volume and intensity, while allowing for an extended recovery period. By rotating through all the major muscle groups, you ensure that each one gets the attention it needs to grow, while also giving your body the time it needs to repair and come back stronger. Here’s why this method might be the game-changer you’ve been searching for.
