So the news is out: The top two fitness trends for 2014 are high-intensity interval training, (ie P90X) and body-weight training (push-ups, pull-ups, sit-ups and planks) according to a recent annual fitness trends survey. So how long do we think these trends will last? Push ups and pull ups have been around forever, so is it like fashion, and if you wait around long enough, it will come back 'in style'? I'm just glad it's back because these workouts can be done anywhere, anytime! For the record, I expect TRX to be BIG in 2014 as well!
