According to the new study, apparently so. Researchers at Ohio State University assigned 54 healthy participants to a five-day per week CrossFit-based exercise program that lasted ten weeks. The 43 participants that competed the program saw incredible improvements in measures of aerobic fitness and body composition. Maximum aerobic capacity grew by 13.6% for men and 11.8% for women. At the same time, male participants' body fat decreased from 22.2% to 18% and female participants' fell from 26.6% to 23.2%. Both men and women also enjoyed significant increases in lean muscle mass. What's more, the improvements in aerobic fitness and body composition were significant when broken down across participants' initial fitness levels. In other words, people of all shapes and sizes saw tremendous physical improvements.
