Acute exercise increases expression of telomere protective genes in heart tissue

There's not much evidence for that, and some evidence that heart health is improved by sustained submaximal exercise. In my experience the best improvements I have sustained in overall fitness have been from either very short, very brutal exercise (NOT just splitting up a dose of 30 minutes into easy sections) or from chilling out for 40-60 minutes at comparatively easy pace. The latter has been something that you can do all the time; the harsh interval training is something that seems to work in 2-3 week bursts with time off afterwards.

Anything is a lot better than nothing, but there is some evidence that there are all sorts of good effects from a longer session once in a while.

The other thing about phasing in short brutal intervals for a few weeks and mostly doing Long Slow Distance ("LSD") is that it's either over quickly or it's quite pleasant. I get most of the exercise in the more painful 'middle' of this continuum from sport.

EDIT: here's the article that got me interested in LSD style training. https://www.elitefts.com/education/training/echocardiography...

Thank you for the link! Anything sure is bound to be better than nothing, I limit my sessions to 1 hour but alternate between doing an hour of constant excercise at a slower speed (I'm a swimmer), and doing shorter burts of intensive excercise but then taking a minute or two break after 2 lanes.

Either way, I think it's easier to go for an hour 3 times a week, than doing half an hour each day. (would become a bit more pricey, and I'd lose the time of going to the pool and back each day. Not as easy to combine with other responsibilities imo)
