The short answer is… Both. You can technically build muscle doing either low or high rep sets under load, but each have their limitations. High rep sets (e.g. 20 reps) 🏋️It’s harder to gauge how close you are to failure which is a must for stimulating muscle growth 🏋️You may be limited by cardiovascular fitness - definitely an issue when training legs 🏋️They hurt - so it may be difficult for you to push hard and endure the discomfort Low rep sets (e.g. 5 reps) 🏋️Put more stress on the nervous system 🏋️Riskier if your form is not fully dialed in - heavier loads put more force on ligaments and cartilage So, what’s the optimal way to stimulate muscle growth? Most of the time it’s somewhere right in the middle…a rep range of 8-10 reps is popular because it works. Still not sure what to do? Book yourself in for a free assessment with one of our coaches.
