I started GST a little more than 4 months ago to increase my range of motion and strength so that I'd be 1) a healthier human and 2) more durable in the sports I enjoy (mountain biking, trail running, BMX...). I'd say I have no interest in gymnastics as an end in itself. I don't care about Planches and Mannas. I get that they are real accomplishments, but they don't light my fire.
If that's really my goal - increased durability in other pursuits, am I in the right place? When I heard Coach Sommer on Barbell Shrugged, I immediately thought that I wanted what he described. Strengthen the joints and build strength over a complete range of motion. I've had a lot of injuries over the last years that I think I wouldn't have had if my joints were stronger and held together better in crashes or even mis-steps.
As far as reward for the last 4 months: when I mountain bike my wrists don't hurt anymore, my upper body is far more stable so I can control the bike better when the trail is particularly rough, I'm more able to steer with my hips (which lets me carry more speed through turns) and my upper body never sags between my shoulders (thank you, thousands of Scapular Shrugs!) I haven't had the chance to see if I'm more durable when I rag doll down a mountain. I also noticed that when I run, my feet are straighter, not pointing out to the side as much (thank you endless Swivel Hips!)
Just an observation: 20 years of cycling combined with 30 years of desk work is not good prep for ABH.
