Push-ups are a fundamental bodyweight exercise that engage multiple muscle groups, predominantly targeting the chest, shoulders, and triceps. They also involve the core, helping to build strength and stability in that area. When asking if “40 push-ups are good,” it depends on the context in which you’re measuring “good.”
In terms of overall fitness and upper body strength for an average adult, being able to perform 40 consecutive push-ups is a commendable feat. Most people might struggle to do half that number with proper form. If you can do 40 push-ups without stopping, it’s an indication that you have a strong upper body and good muscular endurance.
However, when it comes to achieving visible six-pack abs, push-ups are only a piece of the puzzle. They do engage the core to some extent, but they are not primarily a core-focused exercise. To develop visible abs, you need two main things: a low enough body fat percentage to reveal the muscles, and well-developed abdominal muscles. Push-ups can contribute to building a strong core foundation, but you’d also need to incorporate specific exercises targeting the abs and obliques.
Another thing to consider is body fat percentage. Even with a strong core, a layer of fat can obscure the muscles, preventing them from being visible. Therefore, in addition to strength training, you’d also need to manage your diet and potentially incorporate cardiovascular exercises to reduce body fat.
To summarize, while 40 push-ups indicate good upper body strength and endurance, achieving visible six-pack abs requires a combination of core-specific exercises, overall body strength training, and effective dietary and cardio practices. Push-ups can be a part of the journey, but they are not the only exercise to focus on for that specific goal.
