If you want to maximize muscle growth with weight training, there’s a simple concept to grasp: push your muscles to the point of momentary muscle failure. This means working out until your muscles are so tired that they can’t do another rep, which forces them to recruit more muscle fibers and grow stronger.
But reaching muscle failure isn’t as straightforward as it sounds. It requires a lot of dedication and discipline. Most people decide beforehand how many reps they intend to do. For example, you might think, “I’ll do ten reps.” However, stopping at ten reps often means you haven’t truly reached muscle failure. Your muscles don’t know what “ten” means; they only know they’re being pushed until they can’t complete another rep with good form.
So, the most common question is, “How many reps should I do?” The truth is, you should do as many reps as you can while maintaining good form. This approach will push your muscles to grow and get stronger during the recovery period between workouts. Without pushing to failure, muscle and strength improvements will be slower.
Unfortunately, many people pre-determine their reps and ignore the concept of muscle failure, which is a big mistake. Instead, you should focus on doing as many quality reps as possible each time you work out.
One drawback of this intense training is the risk of overtraining. If you overdo it, your progress may actually suffer. High-intensity strength training should be short and focused, with a few exercises and sets, allowing for adequate recovery between sessions. Remember, muscles don’t grow during the workout; they grow stronger during the recovery period that involves time, rest, and nutrition.
Another downside of pushing to muscle failure is the tendency to lose proper form. It’s crucial to maintain a slow, controlled motion and full range of movement for each exercise. This means moving through the full extent of the exercise to get the best results.
