Yes, the 10 x 10 rep set range is an effective way to build muscle. The idea behind this 10 sets approach is that with a high volume of work, the muscles will be forced to adapt and grow in size and strength. This is achieved by forcing the muscles to move heavier loads than they are accustomed to, which stimulates muscle growth. Additionally, the short rest periods between sets forces the muscles to work harder and longer, leading to greater gains in muscle mass and strength – aka ‘Growth Mode’.
