A lot of times swimmers find because they have limited mobility due to tight and stiff muscles a yoga class be a struggle. When you add that on top of the demands of the sport it can become too much.
There are many different styles and types of yoga because of that reason a practice can be tailored specifically for recovery without any struggle involved, no matter how tight you are.
One of the most effective ways to enhance recovery is through restorative yoga. In restorative yoga you use props to support the body in different poses, which in turn encourages and allows the body to let go. This style of yoga will also engage the parasympathetic nervous system which allows the body to recover even more effectively.
