Ok been reading about how to stay in good shape and came across this idea of spending 200-300 per minutes per week exercising. Get exercising and get your heart rate up, but so that you can still speak at the same time. If you are just starting up work your way into it, if you are into weights do more reps instead of more weight.
I also like burst training where you train less but increase load each time. Spend less time training and get better results …
