Regular exercise is a huge commitment of time, willpower and physical exertion. Everyone wants to know that the effort they are putting in at the gym will yield maximum results. Here are the most common errors seen in gyms, robbing fitness goers of their fat burning potential.

1. Doing cardio before weight training

Those who choose to get their cardio out of the way before completing their resistance training might not be optimising their fat-burning potential. By doing your weight training first, you empty your glycogen stores (your main source of energy). Following your weights session with cardio, with depleted glycogen stores actually results in greater fat loss Tip: After your resistance training, go for 20-30 minutes of low intensity cardio for better fat burning

2. Not changing your exercise program

How long should you do the same exercise program for before changing the exercises, number of repetitions and weight? Every 3-6 weeks. This principle is fundamental to any professionally written exercise program, but is underused in most gym programs.

3. Doing low intensity cardio

Half an hour on the treadmill may not be as useful for fat loss as once was thought. Research suggests that performing high intensity interval training (HIIT) is much more effective for fat loss than traditional low intensity cardio. HIIT is only recommended for healthy people with a reasonable level of cardiovascular fitness.

4. Doing ab crunches to lose belly fat

A common misconception is that doing abdominal exercises are the key to fat loss. Doing 150 ab crunches a day can strengthen your abdominal muscles, but will not make them any more visible unless you take an integrated nutritional, lifestyle and activity approach to reduce your overall body fat. Tip: Try Air squats, Burpees or any other full body exercise for better fat loss.
