You can try all sorts of functional exercises and make hacks to increase your lifting capacity. However, if your grip does not match the snuff, you will never be able to move more weight during upper body workouts.
More importantly, grip strength can be an important indicator of your overall health. Therefore, Men's Health Fitness Director Ebenezer Samuel, C.S.C.S. takes every opportunity to train with exercises that challenge his grip while touching other muscle groups like this towel-rack series.
To complete the exercise, you will need a towel and dumbbell and a bench to lean on. If you want a set of weights to try this at home, check out this Bowflex adjustable set.
Samuel warns against overdoing it. "Go easier than usual," he says. "Start about 10 to 20 pounds lighter than your regular dumbbell row."
