Conventional wisdom on building muscle has long held that intense workouts and subsequent soreness were necessary for growth. However, recent scientific research suggests a more nuanced approach.
The 'tear and repair' model, popular among old-school trainers, posits that muscle damage triggers the body's natural repair processes, leading to increased size and strength. While this theory may have worked for some lifters, especially those using performance-enhancing substances, it appears that there is another way to build muscle.
According to Dr Anne Brady, a kinesiology professor specializing in muscle quality, physical function, and body composition, the primary driver of muscle hypertrophy (growth) is actually mechanical tension. This means that lifting weights heavy enough to create significant physical strain on your muscles is more important than simply causing micro-tears.
Muscle damage does play a role in the growth process, but it's not the main factor. Instead, it seems to be more like a side effect of using sufficient physical tension and mechanical stress. In other words, if you're lifting enough weights or performing enough repetitions to strain your muscle fibres, that can contribute to muscle growth.
However, this doesn't mean that feeling pain during or after a workout is always an indicator of progress. There are many cases where people have experienced significant muscle growth without substantial soreness. Conversely, excessive soreness doesn't necessarily guarantee increased strength.
The key to effective muscle growth appears to be a combination of heavy enough weights to create mechanical tension and sufficient repetition to generate metabolic stress. When you combine these two factors, you can stimulate both myofibrillar (strength gain) and sarcoplasmic (size gain) hypertrophy.
In practical terms, this means that you don't need to push yourself to extreme limits or worry excessively about minor details during your workouts. While progressive overload is still essential for making muscles stronger, it doesn't have to mean obsessing over trivial matters. A more relaxed approach to training, with gradual increases in weight and repetition over time, can lead to significant gains in both strength and muscle mass.
