The pull-up is a multi-joint bodyweight exercise that builds strength and muscle in the upper back, biceps, and core. It is often used as a measurement tool in military or tactical fitness tests, and is an excellent gauge of “relative strength” which is strength in relation to bodyweight.

Requires no equipment other than a bar
Can build absolute strength for low reps, or strength endurance for higher reps
Easy to alter grip style and width to target different muscles or rep ranges
