High Reps - Low Load Vs. Low Reps - High Load for Muscle Building

High Reps - Low Load vs Low Reps - High Load for muscle building:

Traditionally, weight lifting in the range of 8 to 12 reps to failure was considered the most effective for building muscle. Studies now suggest that higher reps and lighter loads may be just as effective. I have also noticed this with novice weight lifters at the studio, where initial circuit training using sets of 15 to 20 reps yields significant gains in both strength and muscle mass. This article by Christian Finn looks at some of the evidence to support this: https://muscleevo.net/low-weight-high-reps/
