After 22 years of treating physical therapy patients and 30 years of working with adult fitness enthusiasts, it has become very clear to me what you need to do within your workout routine to eliminate nagging joint pain and muscle stiffness.
Developing a strong mid back is going to be the key to avoiding a lot of nagging issues with your shoulder, neck and low back. The good news is by applying RBT into your workouts, you will be training your back, abs and glutes all at one time with every exercise.
The chest is one of those muscle groups that when trained wrong can lead to long term shoulder rotator cuff or cartilage issues. Resisted push up variations are obviously the best way to train absolute chest strength using resistance bands.
