You know that feeling when you are exercising, and you come to a point where your muscles simply cannot complete another rep? One might assume that it’s just because the muscles are tired. However, Trevor Thieme, a strength coach and former fitness editor at Men’s Health, explains that things are not so simple, and how the Central Nervous System is involved.
- When you exercise, your body works to produce energy to keep up, which leads to metabolic waste products accumulating in the muscles.
- Your body has a fail-safe built in to make sure that you don’t hurt yourself from over-exertion.
- If you want the best outcome from your workouts, do the toughest exercises which use more of your muscle groups at the beginning of your sessions.
