Secret behind Arjun Kapoor's six-pack abs revealed (see pics)

New Delhi: Actor Arjun Kapoor's sculpted muscles have surely helped him to gain women's attentions. His trainer Kyle Arthur says the secret lies in fitness programme called RAW28."I have developed a programme to sculpt, shape and develop Arjun's physique into something truly impressive. I call this plan, RAW28. We have used this plan in recent weeks to ‘shock' the body, to produce a new stimulus and force the body to adapt," Arthur told IANS."RAW28 is the complete mixture of strength, endurance, and functional training to ensure the body is always guessing what's next, and that's the key to adaptation," he added.Arthur said he and the "Ishaqzaade" star set objectives that would allow them to train effectively, but also to ensure the training being endured was enjoyable and would provide the mental stimulation enough to allow for 12-hour work days and remain motivated to exercise.The trainer has introduced high intensity interval training (HIIT), which consists of sets of 100 percent output followed by timed rest periods."This has allowed for much greater fat loss than the use of conventional ‘cardio' paired with increased testosterone levels and a rapid increase in his metabolism. I have Arjun training with weights four times a week entwined with our personalised HIIT sessions, cross-fit inspired sessions, and functional sessions.""The training, specifically the combination of training, is taken from a system of my creation; the RAW28 programme," he said.Diet is also important, so the nutrition plan on the RAW28 programme has been designed to support significant fat loss, build lean muscle tissue, and even gain strength."It starts with a breakdown of ‘macro-nutrients' - carbohydratess, proteins and fats. Once these are broken down we accumulate the necessary ratios and then we are ready to choose the most appropriate foods to fit these ratios - for example, a diet of 2500 kilocalories may consist of 40 percent protein, 40 percent carbohydrate and 20 percent fats."Arthur says sports supplements will never replace food and a good nutrition plan. However, they are crucial for anyone wanting to push their bodies to the max, which Arjun has certainly been doing while on the RAW28 plan.
