Yes Bonnie I'm gonna have to find that sweet spot again where I gain, but slowly. This is more fun than taking off
The only sweet spot I've heard of is in a golf club. Great for golfers perhaps, but I don't think Golf is highly intensive on the muscles. Mild at best I'd suggest, but having barely ever played it, (was awful when I did), I can't attest as to whether Golf has considerable anabolic effects or not.
