I subscribed to GB unlimited 10 days ago, couldn’t do the crab position and the ape posture, took me 1 week to begin the workout that is tailored for beginners. Today 18 Nov 2018 did the core workout realized that my body is -10 for a scale 0-plus10. During the workout felt the abdomen and the spine, so in my opinion, the exercises are great because they work on the range of motion and fascia as well as the muscles. I’ll do weekly notes and am glad that chose GB unlimited.
