I know this is a bodybuiliding homepage but there have been quit a few articles discussing MMA for example and that is just one sport where cardio plays a huge role alongside strength. Other sports I can think of are rugby and rowing. In all of those strength is vital but it's nothing without endurance. How are you supposed to train for that?
In practice what happens is that especially rowers have a 90-200 minute cardio session followed by weight training... I wonder how much benefit there even is in a weight session after long cardio. Is there a T-Nation author who has some experience and can offer some answers?
