Why You Need To Incorporate Fast-Twitch Exercises Into Your Routine STAT “We train in the gym to get better at life,” not just to perform better in the gym, says JJ Virgin, CNS, a certified holistic nutritionist and personal trainer.According to Virgin, the work you put in at the gym pays forward in the most practical ways—independently standing up from a chair when you’re 90 years old or playing pickleball like a pro at 65.
For example, if you stick with only slow movements, they will become slow-twitch muscles to support that. If you incorporate sprints and jumps into your routine, they may become more fast-twitch, Virgin explains.This, she says, is why you should add fast-twitch movements to your routine for strength longevity.
