Metafit is a High intensity interval session (HIIT) that only takes 30mins but lasts 24hours.This type of training helps speed up your metabolism by producing an ‘afterburn’ effect once the workout is over. So when you are sitting at home watching MKR or the voice you are still burning up to 500 Cals 24 hours after the workout is over. The more lean muscle you have in your body the greater the afterburn effect. A good HIIT session alongside a strength program as part of your weekly exercise routine is the most effective way to burn fat, change the shape of your body and increase your lean muscle tissue.
Cardio done at a higher intensity for a shorter period of time will not only help you maintain your muscle, but can actually help you build muscle mass. When you train at a slow and steady pace for a longer period of time, you are training your muscle fibers to be more aerobic and have greater endurance
Do you know how muscle fibers adapt to becoming more aerobic and gaining greater endurance? By becoming smaller and weaker! The smaller a muscle fiber is, the less time it takes for nutrients to travel within the muscle fiber. This speeds up the rate that the nutrients can be burned for fuel.
But even if you think of this from a common sense perspective, it makes perfect sense. Stating that slow and steady cardio for longer periods of time is best for maintaining muscle mass is similar to saying that curling 5 kilo dumbbells for 30 minutes straight will build more muscle than curling 20 kilo dumbbells for sets of 10 reps with 2 minutes of rest between sets. See, the higher-intensity workout clearly builds muscle better. If you think about it, weightlifting is actually a form of HIIT!
