Just wanted to share some a product with other guitarist or really anyone who sits to practice their instrument. There was a point i was practicing 4-5hr a day, I was really determined to improve my playing, but those hours were literally killing my legs and back. A year later of doing that my playing has improved but my back and legs got worse. I looked into the guitar chair, different padding chairs, drum thrones and pretty much tried everything. And of the course the answer is was always in front of me, taking breaks helped with my leg problems, sometimes I forget about my body awareness and somehow my legs dig into the ground and lock up. Taking a break every now and then has help, but there is another thing that has greatly helped and it a small posture support that is called back joy. You can google back joy but what it is- a pad that you sit on. You can put it in any chair that you currently practice with. I've used this in three different chairs and it really does take some relief off the back and helps correct my sitting. A family member let me borrow one and it is very helpful! and most of all it is a somewhat cheaper alternative to buying a whole new chair just to practice CG. It is also portable enough to carry around and use in your car, office chair etc. I love it for practicing and I will soon get one for my studio so that it may help my students with their posture. Just wanted to pass this on.
