You *should* do Strength in the Off-Season to Improve Your Cycling
Studies and practical experience from top athletes in the elite and masters ranks show us that that strength training can increase our on bike performance AND make us more resilient to injury. You need only look at athletes like Nino Shurter and 2018 MTB World Champion Kate Courtney for elite examples of strength training and general athletism!
Remember you are a person, not (likely) a Tour Pro (or NFL Pro…)
But what should you do for strength to improve your cycling?
Your first priority is to get used to strength. Getting in the gym and moving through a range of motion in the fundamental movements. Squat, Hinge, Push, Pull. Many of us are best served working on limiters in range of motion and to get used to moving well. This may take several months of work but you will see improvements each session, and if you stick with it for a few months you will notice you feel stronger, more stable on the bike and likely less stiff and tired throughout the day. The trick is what exactly should you do? How many reps? How many sets? How many exercises?
