The popularity of High-intensity interval training (HIIT) has soared high in the recent past. This form of workout helps to burn loads of calories in a very short period of time, which has made it popular among fitness enthusiasts. It is excellent for people trying to lose weight and build muscle if performed properly under the guidance of an expert. But performing this workout can be harmful to a person in the following four conditions.
If you have a heart problem
HIIT is a very intense form of workout, which puts a lot of burden on one’s heart. While performing HIIT, your working muscles demand more oxygen. For the transportation of oxygen, your body has to work extra, which puts a lot of pressure on your heart and cardio respiratory system. In general, this kind of stress makes your heart stronger. But if you are suffering from a cardiac problem, then it can backfire. In case you smoke, the risk can be even higher. Just to be safe, consult your doctor before going for this form of exercise.
If you are new to exercise
If you are someone who has just started exercising, then do not try to perform HIIT immediately. Take things slow and get into the system first before attempting HIIT. Your muscles and tissues are not strong enough right now to handle this kind of high-intensity training. If you will try to do HIIT in the first-week, you might get injured or strain your muscles. Build your base first and then move ahead.
If you are injured
If you are injured or your muscles are strained then try to stay away from this form of workout. HIIT puts a lot of stress on your muscles, joints, tendons, and ligaments and chances are that you might end up hurting yourself. Stick to a gentler form of exercise while you recover.
If you do it more than often
HIIT is not something to do every day. This exercise puts a lot of load on the body and hence should be performed only once or twice in a week. Keeping a gap between your high-intensity workout days will give your muscles, joints, and tendons, a chance to recover from your last session.
