But wait there’s more! 😀

Those are the energy systems in the muscles and which ones adapt more to which stimulus. The heart itself is experiencing different demands …

During aerobic exercise the heart is experiencing sustained volume overload, delivering more blood to muscles against normal or even decreased vascular resistance. Over a matter of just a few months of training the heart adapts by increasing stroke volume, all chambers enlarge and specifically the left ventricle wall thickens.

Resistance training is a pressure overload rather than a volume overload state. It does not tend to increase stroke volume and the heart remodeling is modest thickening of all walls concentrically.

Combining both approaches is [most effective](https://pmc.ncbi.nlm.nih.gov/articles/PMC6322789/).

> In conclusion, among individuals at an increased risk for CVD, as little as 8-weeks of combined training may provide more comprehensive CVD benefits compared to time-matched aerobic or resistance training alone.

Not sure what happened to you @Spice_Weasel but I’d give yourself a good recovery day and then a lighter active recovery exercise day in any case.
