How to Choose the Right Amount of Exercise to Improve Muscle and Strength
Does the bro science rep range check out?
If the clock is your primary guide to determining your exercise dose then you are likely over or under-training.
There is nothing special about an hour.
Granted, I am a huge proponent of the physical activity guidelines, and they use time thresholds for exercise: 150 minutes of moderate or 75 minutes of intense aerobic physical activity a week. The recommendation of two strength training sessions per week lack doesn’t have a time marker.
These recommendations are baselines for health and wellness, not universal markers for all potential fitness goals.
If you want to run a marathon, 150 minutes a week won’t cut it. On the flip side, if you use high-intensity interval training, you can improve your cardiac capacity with three weekly 4-minute Tabata sessions. Keep in mind a Tabata workout is not any exercise for 20 seconds on and 10 seconds off. It is a brutal max effort protocol on a cycle ergometer.
There isn’t a one-size-fits-all approach to optimizing training. We can provide universal recommendations for baseline fitness, but even that likely needs some adjustment considering training history, age, and current health status.
