About 15 years ago there was a relatively seismic shift in fitness as CrossFit gyms began popping all over while simultaneously there was research coming out showing the benefits of HIIT (High Intensity Interval Training). The average gym goer who would traditionally work down a row of selectorized machines for 3 sets of 10 and finish up with 30 minutes on a cardio machine were now doing Olympic barbell lifts, jumping on boxes and doing burpees until they verged on vomiting.
A recent study has now questioned whether this hybrid, or what is called concurrent training, is as effective as separating your strength and cardio training. The sexy headline is that the participants who did this separation in their training gained fitness twice as fast as the combined/hybrid training group.
