Remember when you used to spend ages hanging from the monkey bars as a kid? Well, consider this playtime take two. If your grip isn’t solid, you’ve got no chance of lifting yourself up, so develop strength by holding on to the pull-up bar with your legs hanging beneath you. Hold for 10-30 secs and aim for 3-5 reps. Speaking of grip, for pull-ups, hands are pronated (palms facing away from you) – turn them towards you and it becomes a chin-up, which is slightly easier.
