One of the keys to adding more muscle in less time is to work the target muscles as hard as you can, then back off to give them enough time to recover and grow. This workout does just that – not only by putting your biceps and triceps under a lot of muscular tension, but also by tapping into both fast-twitch and slow-twitch muscle fibres to prompt a greater post-workout growth response. That’s why both of the two tri-sets in this workout – the first targeting your biceps, the second your triceps – use three different rep ranges for each of the three moves, with very little rest in between.
It starts with a six-rep compound move to fire up your central nervous system to activate more fibres, then there’s a 12-rep isolation lift to work the muscles closer to fatigue. The final 25-rep move will force muscle fibres that don’t usually get worked during straight sets to kick into action. The result: a big muscular pump and more damage to the muscles, creating the ideal conditions for adding more size.
