A high degree of activity might cause vertebral strength to outnumber disc strength. Physical exercise strengthens both the vertebrae and the discs, according to research conducted by Porter et al. In addition, most exercise programs have a few days of rest between hundreds of reps, allowing for adaptation and tissue recovery. The number of flexion and extension cycles used in the studies showing intervertebral disc herniations is also different from a normal exercise program, which usually only has a few tens of repetitions per set rather than thousands. Another thing to consider is that the porcine spine has a much smaller range of motion than the human spine during flexion and extension, as shown in a study by Alini et al. The porcine model was subjected to 4,000 to 85,000 cycles of repetitive flexion and extension, resulting in most of the discs showing complete or partial herniation.Īlthough these should be a cause for concern, keep in mind that the porcine model in these studies may not function precisely the same in normal movements as the muscles and other surrounding tissues were removed from the spine. Their studies subjected the porcine spine to high-volume cycles of flexion and extension with resistance similar to that in crunches. have demonstrated that repeated flexion and extension motions contribute to intervertebral disc herniation. In addition, studies by Drake et al., Tampier et al., and Callaghan et al. The concern is that high volumes of repetitive spine flexion may speed up spinal disc deterioration, as shown in studies using an ex-vivo porcine model. The crunch has become a topic of contention among sports coaches, personal trainers, and fitness buffs. However, these studies were conducted ex-vivo, meaning they were conducted away from a live organism hence, the precise risk-to-benefit ratio remains to be determined. The easiest variation would be hands on the sides of the body, as it provides the least resistance for the exercise.Įven though crunches are very effective exercises for developing the abdominal muscles, in recent years, they have come under a lot of flak due to evidence from studies indicating that they have a detrimental effect on spinal health. For example, the hands can be placed behind the head, across the chest, or on the sides of the body. One may vary the resistance of the exercise by positioning the hands on the body in various ways. The tuck crunch may be performed on almost any flat surface and requires the individual to flex their spine repeatedly. One of these variants, the tuck crunch, has gained popularity because of its simplicity and convenience. Most individuals, regardless of whether they are serious athletes or go to the gym on occasion, have a set series of crunches that they do to enhance both their looks and the power of their core muscles. Note: she said to repeat three rounds of these exercises as a quick core circuit.Exercise routines have traditionally consisted of the abdominal crunch and its many iterations. Ahead, check out four moves you can do with sliders, straight from Megan. Or if you're working out on carpet, you can use paper plates. But you can opt for socks or a towel if you don't have any sliders on hand. "Adding a slider to a functional exercise, like a plank, just creates a more advanced exercise, which I love." In Megan's class, we used two sliders, one on each foot, for multiple variations of planks. I think they're so effective," Megan told POPSUGAR. "I love a plank, just because it's really a full-body movement, but you're obviously feeling your core the most. She also has a dance degree from NYU's Tisch School of The Arts, and after taking The Sculpt Society class sponsored by Propel Vitamin Boost, I spoke with her about the one thing she uses to make these exercises more challenging. And, if one person knows how to up the intensity on a plank, it's The Sculpt Society founder and ACE-certified personal trainer Megan Roup. Planks work the deepest parts of your abs, so they really do rock you to your core.
