What is the best way to grip the pullup bar? It depends. I think a wide variety of grips can make your pullup workouts more enjoyable and diversify the strain on wrists, elbows, shoulders, joints, and muscles. But what is the best way to grab the bar? That also depends.

Grabbing the Bar
Depending on the grip you select and how many pull-ups you plan to do in a workout, you may want to consider how you grab the bar. One of the ongoing debates in the fitness world is where the thumbs go when the bar is grabbed. I call these grips the barbell grip and the mountain climber grip. 

A classic workout incorporating all the grips is the half pyramid repeated five times, one for each grip. This workout totals 150 pullups in a single workout, but you can adjust to 100 total repetitions by not doing the 10-rep set below:

Regular Pullup – 2,4,6,8,10
Reverse Pullup - 2,4,6,8,10
Close Pullup - 2,4,6,8,10
Wide Pullup – 2,4,6,8,10
Commando Pullup - 2,4,6,8,10

Discussions on pull-ups are popular mainly because they are so difficult. The percentages of men and women able to perform one unassisted pullup are low, as this exercise is the “heavy weightlifting” of the calisthenics world.  As a nation that is increasingly getting heavier and heavier every decade, the statistics will likely continue in the negative direction until we get stronger and lose weight (generically speaking).
