You can get great benefits from doing it for 5 minutes after you lift...researchers found it created huge spikes in Growth Hormone versus people who did no HIIT after lifting. Also properly done Tabata is only 6 minutes long, but might be among the hardest things to actually accomplish in the gym.Most people don't know what intense cardio is. You should be completely gassed, lungs on fire, and near total exertion. Typically it takes sprints, or wrestling. But if you do actual high-intensity cardio, then yes there are a lot of benefits to it. 4-6 hours post-workout, your body will convert even junk carbs to muscle. Most guys I knew from mma were ripped, but ate garbage. I drank a 6-pack of beer every night, and still had very low body fat. I don't know if 15 min is enough, the studies were done on wrestlers who practiced 2 hours, but there are other health benefits to high-intensity cardio as well.
