While the safety of CrossFit workouts depend on the person doing them and the instructor, speed and intensity tend to be prioritized over technique in many CrossFit workouts. The socially supportive atmosphere can be motivating, but it can also make participants feel pressured into lifting more or doing more repetitions than they should.
In addition, the workout tends to be a one-size-fits-all approach, and certain exercises can be dangerous for older people or for those new to working out. In one study, published earlier this year in the Journal of Strength and Conditioning Research, nine of the 54 participants recruited – or 16 percent – dropped out due to “overuse or injury.”
Critics of CrossFit have even linked it to rhabdomyolysis, a serious condition that results from the breakdown of muscle cells.
Bottom line: If you want the full body workout benefits of CrossFit without the high risk, be sure to do your research. Aim for a class with smaller teacher-to-student ratios and look for an instructor that cares about technique, respects limits and has more training than just CrossFit certification.
Contrary to popular belief, the body is already continually working to cleanse itself, and needs nutrients to do so – including protein. According to Nielsen, many fast-based detox diets hamper your body’s detoxing capabilities, and can also “disturb the balance of healthy bacteria in the digestive tract.” Healthy detox diets should cut out alcohol and junk food, include a great deal of foods that have natural cleansing properties, like broccoli, kale and collard greens, and shouldn’t leave you ravenous.
That said, a couple weeks of detoxing a year won’t have a lasting difference on your health. “One of the big misconceptions is that you can cleanse for one or two weeks a year and go back to your normal diet,” says Nielsen. Instead, detox diets are useful when the results you feel, like increased energy, inspire you to incorporate healthy habits for the long term.
