At the end of a long season, footballers often use the summer months to try different types of training to maintain their hard earned fitness.
Tottenham full-back Kyle Walker pays regular visits to his local boxing gym, while Bayern Munich winger Arjen Robben is a fan of cycling.

Another way of keeping fit is to jump on the rowing machine at your gym - Brentford’s Head of Athletic Conditioning, Chris Haslam, explains why.
"Rowing is an excellent way to maintain both aerobic fitness, which you need for long distance running, and anaerobic fitness, which is high intensity work which gets your heart rate up, during the off-season,” he says to FourFourTwo.
“Rowing also minimises the amount of additional load you place on those fatigued legs, which are often the result of an intense season.
“I always prefer to work using distances to achieve as this gives the athlete a way to monitor improvement in a simple format. Here are some sessions you can try this summer.”
