'I do a mix of high intensity weights, heavy weights, and then cardio,' he explained.

He also added the importance of diet as well as exercise, saying: 'But 90% of what you do is what you eat and so for me I go on a very high protein, low carb diet, and I find it works for me but everyone is different'.
