My main criteria with cardiovascular activity is really if xyz activity in real life is difficult because of a lack of it. I sometimes go for a short jog or do some sprint intervals, I like swimming but don't do it very often, I cycle to/from town now and again, I get plenty of brisk walking in... none of which is difficult or gets me too out of breathe (and having been a big fatty who did zero exercise, I know what wheezy-unfit-sweaty rolls feels like), other than when I occasionally have to leg it for the train, but I challenge anyone to get from the Jubilee stop at London Bridge to the train platforms at LB station as quick as they can with a bag full of stuff and not need to catch their breath for a moment!
I don't feel the need to do things like MetCon/muscular endurancy stuff too much because I don't play any sports / activities that require it; I'm just an office worker who'd like to look good naked, be fairly strong for my size and keep my body ticking along for as long as possible, which tbh doesn't require nearly as much effort as those performing athletic feats and pushing the limits in some competitive or professional environment. If people want to do that stuff, great, but for me I'd prefer to keep time in the gym/exercising as time-efficient as I can so that I have more time for real life stuff.
Those leg muscles !"!!!!!!
