Anaerobic exercise - explained - This form of exercise involves working at a highly intense level where your heart is beating at 90 -100% of your maximum heart rate. Be- cause of the in- tense nature of anaerobic ex- ercise, it can only last for short pe- riods because your c ardiova scu- lar system can not deliver the oxygen needed to your muscles fast enough. On the plus side though, it means the time spent working out can be much shorter and therefore can be a time efficient way of exercising. This is a very challenging way of exercising, so don't start here if you're a begin- ner. Going too hard and fast could put you at serious risk of injury and dis- comfort. As with any exercise, pro- ceed with medical advice before un- dertaking any ac- tivity.
