Learn Pilates, which is both strength training and agility training in one!
Pilates largely avoids high impact, high power output, and heavy muscular and skeletal loading. The system focuses on quality rather than quantity - not many repetitions, but instead a selection of exercises that are performed using concentration and control. The method is based on the mind controlling the muscles.
The Pilates system was developed in the 1900th century and was for a long time a secret form of training for dancers and athletes who trained after injuries. The German Josef Pilates, the founder of the method, originally called it "Contrology".
The goal of Pilates is to train different muscles to strengthen and tighten the body, while developing proper breathing, a good posture, and mental concentration and attention.
Good for both body and soul.
