Spring is on it’s way have you hit the mat for your sit ups and crunches yet?! Well we are here to tell you not to! That’s right, we said no sit-ups or crunches! Why do you ask? There is actual research now showing the negative effects of situps/crunches on the lower back – especially if you have a pre-existing lower back condition. Dr. Stuart McGill from Waterloo University has dedicated his career to the causes and rehabilitation of low back injuries.
