To many people, the sit-up is the 101 of ab exercises, the one we head to when looking for a stronger stomach. But according to a new report by the BBC, you might actually be causing yourself more harm than good by performing them.
A study conducted at Waterloo University in Canada found that continuous bending of the spine while doing sit-ups could lead to wear and tear and back pain, while another study from Finland discovered that, while genetics play a large role in back injuries, performing sit-ups could increase your odds of injury.
Another interesting piece of research carried out on soldiers stationed at the US military's Fort Bragg attributed 56% of all the injuries sustained during the two-yearly Army Physical Fitness Test, to sit-ups.
We've already shown you how to get a six pack without them, so maybe it's time to ditch the sit-up once and for all?
