Cardio exercises
10 movements that train the cardio directly, each with setup cues, the mistakes to avoid and a substitution for every equipment type.
What cardio trains
Cardio trains the heart, lungs and circulation rather than one muscle. A stronger heart pumps more blood per beat, which is why a fit person's resting pulse is lower and why recovery between hard sets gets easier as conditioning improves.

How to train cardio
Aim for 150 minutes a week at a conversational pace, or about 75 minutes if most of it is hard. A practical mix is two or three easy sessions of 30–45 minutes plus one interval session. Easy cardio does not interfere with lifting; hard intervals the day before a heavy leg session will.
The mistake to avoid
Doing everything at a medium-hard pace. It is tiring enough to hurt recovery and not easy enough to build a base — most of your cardio should feel genuinely easy.
Cardio exercises by equipment
Whatever your gym has — or does not have.
Also works the cardio
