Lower Back Rotational Stretch
Good for: lower back
How to do it: Lie on your back and face the ceiling. Bring your knees up and start with your feet flat on the floor. Then as you keep your shoulders glued the ground, rotate your knees as far to the right as you can without your shoulders lifting up. Hold for a few moments then switch. Move at your own speed and do as many repetitions as you like (just make sure you give both sides the same amount of love).
Behind-the-Back Forearm Grip Stretch
Good for: chest (pecs), shoulders
How to do it: Sit or stand in a comfortable position. Press your shoulders down and away from the ears and squeeze your shoulder blades together. Reach your arms behind you and grab each of your forearms (or elbows if you have that mobility) and pull down. Hold for your desired time.
