Sport-Thieme “Spring King”

The Sport-Thieme “Spring King”: strengthen your upper body muscles
The Sport-Thieme “Spring King” is an elongated iron spring. The flexible weight bar has training resistance, that is exerted by pushing, rather than pulling it. For fitness training, you just need to hold both handles and form a “U” shape with the fitness trainer. The process of pulling your arms in particularly strengthens the chest muscles. But the arms, shoulders and back also benefit.
