For a long time I thought if it wasn't heavy or explosive, it wasn't worth my time. Then I started actually programming MetCons consistently and realized: you CAN get an insane amount of work done in a short window. More than most people think is possible. Don't get it twisted. You still need your anaerobic work. You still need to train for power, speed, and max strength. That doesn't go away. But MetCons give you something most training styles don't: the ability to hit EXTREME VOLUME, put your body under extreme stimulus, and build your engine while you're doing it. It's not cardio. It's not fluff. It's just smart training. If you've been sleeping on them, add one in this week and see what happens. Are you currently programming MetCons, and if not, what's stopping you?
