Are you familiar with the 100 push-ups a day for 30 days challenge? Discover what happens to your body when you take on this challenge. The push-up is an effective bodyweight exercise for strengthening your chest and triceps. However, some individuals go to the extreme and perform 100 push-ups a day for an entire month. Jeremy Ethier, a well-known kinesiologist and fitness trainer, discusses the effects and potential side effects of this challenge. He explains that while you may experience muscle soreness during the first week, your muscles may not have enough time to recover if you continue this routine. Ethier advises incorporating exercises that target your back and shoulders to maintain proper posture. According to Ethier, the challenge itself is not worth it in terms of long-term results. However, it can serve as a motivation to engage in daily workouts.
