When you think about gaining muscle, stretching is probably not first thing that pops into your head. But did you know that stretching plays a critical role in building muscle?Every muscle in your body is enclosed in a bag of tough connective tissue known as fascia. Fascia is important for holding your muscles in their proper place in your body.
But your fascia may also be holding back your muscle growth. Think for a moment about your muscles. You train them and feed them properly. They want to grow and will grow but something is holding them back. They have no room to grow!
Because fascia is so tough, it doesn’t allow muscle room to expand. It is like stuffing a large pillow into a small pillowcase. The size of muscle won’t change regardless of how hard you train or how well you eat because connective tissue around your muscles is constricting muscles within.
The best example of this is calf muscle. The lower leg is riddled with fascia because of its tremendous weight-bearing duties in body. It is because of this fascia that many trainers have great difficulty developing their calves.
The solution: stretching.
Using pillowcase example from above, imagine you can expand size of pillowcase by stretching it. Suddenly, pillow within has more room and will expand to fill that new space.
By stretching your muscles under specific conditions, you can actually stretch your fascia and give your muscles more room to grow.
The key to effective fascial stretching is pump. The best time to stretch to expand bags that are holding in your muscles is when your muscles are pumped up full of blood.
When your muscles are fully pumped up, they are pressing against fascia. By stretching hard at that time, you increase that pressure on fascia greatly, which can lead to expansion of fascia.
