A lot of people think of hamstrings when it comes to stretching, but don’t forget to do spinal and shoulder exercises to increase flexibility. They can really help you out. The spinal twist is a good example. It keeps the hips neutral and it’s very accessible. You can go as far as you can. Anything that feels good and comfortable but is more than your usual range of motion is good. Do 10 reps, holding final twists for 30 seconds each.
