If you are in the acute phase of injury, we suggest managing your pain first before trying out the exercises. Once the pain has lessened, you can do a lower abdominal and core muscle strengthening to help stabilize your spine. You can start with the "drawing in maneuver" just to make sure you are really targeting the core muscles. Once you have mastered that, you can incorporate that technique into any type of strenuous activity you will be performing.
Another exercise we would recommend is the pelvic tilt. You can do this by bending both your knees, placing one hand at the curve of your back, and flatten your back against your hand. This targets your lower abdominal muscles. You can hold for 7-10 seconds and repeat for 10 times.
You can also stretch your hamstrings, with one knee bent for support, and pull your leg with a towel. You can hold for 20-30 seconds and repeat for 3 times.
What we don't recommend you doing are leg raises, sit ups, standing hamstring stretch, overhead lifting and high impact activities.

If any of the exercises aggravate your symptoms, we suggest you stop immediately.
