My Metafit classes in Teddington are based on the principles of high intensity interval training (HIIT).  This involves short intervals of full-on, heart-pumping maximum intensity moves with short recovery breaks in between. HIIT trains and conditions both your anaerobic and aerobic energy systems and offers a number of benefits over exercise where your heart rate is kept more constant.  Here are just a few of the reasons why it’s such a great way to work out.

1. Maximum fat burn. HIIT increases the amount of calories you burn during your exercise session and causes metabolic adaptations that enable you to use more fat as fuel. And it’s the workout that keeps on giving – you continue to burn fat for a whopping 24 hours after a 30-minute class.

2. Muscle is retained. Anyone who has been on a diet knows that you tend to lose muscle mass along with the fat. HIIT workouts enable you to hold on to that hard-earned lean muscle tissue, ensuring most of the weight loss comes from fat stores. Keep the muscle, burn the fat. It’s a win-win situation!

3. A youthful glow. HIIT provides health benefits you simply cannot get from regular aerobics, including a big boost in human growth hormone (HGH). This is great news since HGH is not only responsible for increased caloric burn, but it can slow the ageing process too, so you feel younger inside and out. Forget Botox, HIIT is the secret to eternal youth!

4. No equipment necessary. You can do a HIIT workout anywhere, even in a hotel room!  You don’t need any weights, mats or gadgets – all you need to do is get that heart rate up and lunges, jumps and burpees are simple moves that work brilliantly.

5. Metabolism booster. HIIT not only burns and shed load of calories, it keeps on giving again by giving your metabolism a boost, which is a bonus for anyone embarking on a weight loss programme.

6. It’s efficient! No time?  No problem!  We all have busy lives and fitting in workouts is never easy but with a Metafit class taking less than half an hour, you have a far greater chance of making a routine and sticking to it.

7. Simplicity.  HIIT is tough, there’s no doubt there – but the moves are simple, so there are no fancy routines to remember.  It can also be modified to fit your own level of fitness, so it’s suitable for anyone who is in good health generally.
