go for a check up at the doctors 2 double check. cos if u have asthma, u may need 2 lower your intensity and workload for health and safety reasons.
Major bump on the HIIT. It burns fat so much faster and you won't have to spend 45 minutes 4 times a week running to lose a good amount of fat.Do HIIT (High Intensity Interval Training). It a cardio technique that burns calories up to 24 hours after your work out. What it does is that it doesn't let your heart get use to a steady heart rate. If you jog at a certain speed for an hour your heart would get use to it, you'll still burn calories but there is another way thats better. With HIIT, you jog for one minute, and sprint for a minute, then back to jogging for a minute. This helps you burn more calories and also preserve more muscle. You can also do HIIT on anything that involves cardio, like stairs (run up two-three flights as fast as possible etc), bikes, and also jumping (jump up and touch something 10 times, rest for 30 seconds, go at it again for 15 minutes).
