There is nothing like victory to prove the worth of a training regime. Andy Murray's triumph at the Cincinnati ATP Masters was the result of five consecutive matches in as many days.

There is no doubt Murray has enhanced his physical condition over the past few months, giving him the extra edge to compete with the world's best in the most uninviting court temperatures that the US hard court season often presents. Playing in sweltering heat and humidity drains all energy, so it is to Murray's credit that he could handle the emotional stress in the toughest of environments.

Hard, physical training practices have given Murray that extra belief that he can bounce back from a demanding match and return the next day to produce the same level of intensity and power that is needed for the modern game.

Murray is far more resilient mentally and has proved in the past few months he can come from behind in matches to outfight top-class opponents.

Since Wimbledon, Murray has continued on the same path that saw him come through a strong part of the draw at SW19. He does not look as tired during tough encounters and has learned to channel negative situations, to turn them around and produce some of his best points when it matters.

He can also come through close tie breaks and deliver his best tennis at the most crucial stage of the match. This is something that all top players have the ability to accomplish. This newfound ability is largely because he now has the physical strength which, in turn, is helping his mental game to develop.

He does not become anxious in tense parts of the match as he knows he can play long and last physically till the end, no matter how long he must play. When a player knows they are supremely fit, it takes away the pressure to finish off rallies early and in the Cincinnati final you could see how comfortable Murray was slogging out baseline encounters with the world No.3, Novak Djokovic, a player who Murray has, incidentally, beaten twice in the past two weeks.

There is no question that the hard court season is where Murray has his best chance to win top-tier events. It's a surface suited to his style where he can absorb powerful shots with his solid groundstroke game.

However, over recent months it is clear that he is now able to generate more power from the mid-court area as he is quicker up to short balls where he can muscle shots early to take away opponents' recovery time. This puts more pressure on opponents to keep a deeper length, otherwise Murray will step up and kill them off.

Murray now has a stronger base which is making him tougher to beat but he can now add to this by linking up different styles of play. He will have realised that unless you have a solid base physically and mentally it does not matter how talented you are when you come up against the best in the world.

The top players realise quickly if there is a weakness in an opponent's mental game or if he is not fit enough to go the distance. Players now know Murray is extremely dangerous because he has added a strong base to his talent. If you are going to beat him, you need to not only outclass him you also must outlast him.

All of these factors combined have added another 10% to the young Scot's game and it could not have come at a better time with the Beijing Olympics about to get under way and the last major of the year, the US Open, following later this month.

Murray knows he hasn't made it past the last eight of a grand slam event, but with his newly-developed strengths one knows it can only be a matter of time before he reaps the rewards of all the hard work he has put in.
