Grip strength, how hard you can grip with your hands, which involves everything from your hands to your lats (the large muscles on your back). Almost all actions begin with the grip. Attention to both concentric and eccentric loading for all movements, meaning when our muscles are shortening (concentric) and when they are lengthening (eccentric). In other words, we need to be able to lift the weight up and put it back down, slowly and with control. Rucking down hills is a great way to work on eccentric strength, because it forces you to put on the “brakes.” Pulling motions, at all angles from overhead to in front of you, which also requires grip strength (e.g., pull-ups and rows). Hip-hinging movements, such as the deadlift and squat, but also step-ups, hip-thrusters, and countless single-leg variants of exercises that strengthen the legs, glutes, and lower back.
