Is high intensity training a good idea?

There are a lot of HIIT (high intensity interval training) type work outs online but is this the correct thing to be doing right now? ? High Intensity exercise raises our cortisol levels (the stress hormone). When stress or anxiety levels are already high it may not be wise to raise them further. Stress can impact your immune system and its ability to keep it firing on all cylinders. Obviously exercise is super important for our health, but continually pushing your body to the limit may not be what your body needs right now. Keep moving, but listen to your body, go easier if you are feeling tired or anxious or stressed. Balance intensive exercise with sufficient recovery – enough sleep, good nutrition and mobility exercises. Exercise should be about making you feel good ?
