My boy Nicholas has been working on the monkey bars to increase his grip strength but what can you do when it’s cold and rainy outside? I came up with these grip switches for him to train his one-arm strength inside the gym or on the pullup bar at home. They’re pretty tough, you should try them out at the gym. Every switch counts as one and I highly recommend doing them in sets of ow reps at first. Nicholas has started doing them in max sets. He has worked up to a max set of 63 in this clip and he did it pretty fast. Try it out and let us know what you think.
