Staying Lean For Building Muscle

Staying lean all year makes building muscle MUCH easier. There are two KEY factors here -

1. Insulin sensitivity - you need to be insulin sensitive to make building muscle easier. Being lean has a dramatic effect on this!

2. Aromatisation - the conversion of testosterone to estrogen is never going to be a good thing, especially when you want to build muscle. The aromatase enzyme responsible for this lives in fat cells, making it another reason why staying lean is important for building muscle.
