Claiming pull-ups are simple is ignorant.
In my younger days, an unfamiliar person at the park confidently claimed that breaking the pull-up record was a piece of cake and achievable by anyone. Unfortunately, I failed at it, and I strongly suspect he did too. The pull-up stands as a fundamental exercise, the core of physical fitness. Essentially, it seems like an easy exercise, and indeed, almost everyone can manage a few pull-ups. However, one of the key elements in achieving a multitude of pull-ups is how effectively you maintain your posture.
What does executing a pull-up entail? You grip a horizontal bar, allow your legs to dangle, and raise your body upwards until your chin touches the bar. Simple in theory, but what is the real essence? Are both arms performing equally, or is one exerting more force than the other? Are you utilizing your entire body’s strength, or solely relying on arm muscles? Are you stable, or are your legs swaying? Such subtle nuances can significantly increase the difficulty of doing pull-ups, and you might not even be conscious of them. When attempting a set of pull-ups next, strive to objectively assess how you are pulling your body; you may realize that you have been unknowingly introducing complexities to the process.
If you discover that standard pull-ups do not suit you due to various reasons, consider experimenting with different variations of pull-ups. For instance, some individuals find it easier to grip the bar with palms facing inward, while others prefer the outward-facing grip. It could be beneficial to adjust the number of fingers grasping the bar, or perhaps the bar’s height is not suitable for you. It is acceptable to modulate the exercise’s intensity as long as you compensate with additional repetitions.
