1. More is less
Working muscles until they howl in protest and will no longer lift another gram isn’t the way to increase strength. All this does is deplete your fast-twitch fibres – which are the key to lean growth. Instead, knock back the kilos you’re lifting to a number where you can actually finish all the reps in every set. Working body weight? It’s better to finish six sets of two chin-ups than have an incomplete roster of four sets of three.
