@dpayton Try Walk/Run in intervals - that is probably even more beneficial aerobically; most people believe that running at a constant pace burns more calories and is better aerobically but many studies have not proven that to be the case.
Not saying that the ‘walk’ part should be done slowly - but at the same pace as your current walking velocity; the ‘run’ part shouldn’t be an all out sprint either, but a normal run pace for you.
At first your run times will be much shorter but over time they will naturally increase. The key to all this is ‘ROCKY’ music playing continuously in your head - or for real with earbuds!!🥊🥊🥊😆
