I'm an over-50 runner, a slow one. I'm a nurse frustrated by people not making the most of their bodies. GMB inspires me with gentle movement that slowly and naturally increases flexibility and strength. The videos are repetitive, but my attitude is not. Based on what the cat is doing or if I'm moving furniture out of the way, I hear the training videos reminding me of position points which I had forgotten. It's like being with a trusty trainer who sees that I'm not getting all that I could out of a session. I like owning these sessions forever. I found that I'm not ready for Vitamin yet. That's waiting for me while I continue with Elements to build strength. And yes, I get impatient. So I'm dropping to the floor during the day for pushups or planks, just for fun. Lastly, I cannot outgrow this series. I will be able to follow for years, while I learn to swim, or climb, or continue with hiking etc. I've had frozen shoulder 3 times, so there is a chance I will get it again. I can use this instead of PT. This is truly gold.
