High intensity workouts like CrossFit, Insanity and P90X were a phenomenon this past year and now, according to the American College of Medicine’s Sports Fitness Journal, high-intensity interval training (HIIT), is expected to be the top calorie-burning trend of 2014. While the popularity has increased, so have subsequent injuries.
The HIIT workout is one that centers around high intensity exercises immediately followed by a short period of rest or limited activity. For example: A one-minute sprint on the treadmill followed by a 90-second recovery period or jump rope for three minutes followed by a 45-second walking lunge with alternating hand-to-hand kettlebell exchange. Repeat!! Some HIIT workouts can be completed in as little as 20 minutes.
While the variety of exercises and short time commitment can be tempting to those seeking something besides the boring treadmill routine, these workouts aren’t for everyone. We asked certified personal trainer, Jessica Smith, to give her thoughts on the CrossFit craze. “A good, safe fitness program should be scalable to meet the participants’ fitness levels,” she said. “I’ve seen some programs that do that, and others that really can’t adequately offer modifications that meet all participants needs.”
