Pull-ups, on the other hand, require more upper body strength as they target the back, biceps, and forearms. However, the difficulty of both exercises can be subjective and may vary from person to person. **

An alternative to pull-ups could be inverted rows. Inverted rows are performed by lying under a bar or suspension trainer and pulling your body up towards the bar. This exercise targets the same muscle groups as pull-ups, such as the back, biceps, and shoulders, but it is less challenging for those who may not have the upper body strength to perform pull-ups. Additionally, inverted rows can be easily modified by adjusting the angle of the body to increase or decrease the difficulty. **
