Paul di Resta heads into the new Formula One season fitter and happier than he has ever been in his life.
That is primarily due to a change in trainer, with Di Resta now with David Coulthard's former personal fitness guru Gerry Convy.
Di Resta's fellow Scot has transformed his training regime, and with it there is a new attitude and approach going into the 2012 campaign.
Di Resta has spent the last month at his home in Monaco working out with Coulthard, McLaren's Jenson Button and another Briton in DTM driver Jamie Green.
The announcement came on the day the Scot was the first this year to drive a lap in a new car as Force India unveiled the VJM05 for a shakedown test at Silverstone.
"I'm feeling more comfortable than at the start of last season, which comes with stability and working with the team," said Di Resta, who finished a creditable 13th in the standings on his F1 debut last year.
"I've put in a lot of hours in training in January, upping the fitness level that little bit more, and I must say I'm ready for the challenge. I'm looking forward to getting back into it.
"Working with Gerry has been great. I felt I needed a change to get to the next level.
"He has a schedule in place which is all based upon how I feel, and it's very flexible.
"We speak at 8am, go through how I'm feeling, what's the best way forward, and then I send the results in at 8pm.
"He monitors that, we've done some fitness tests with it, and the fitness level has definitely increased a lot because of that.
"Gerry has been pushing me on and I feel fitter now than a year ago.
"I'm probably training three or four hours a day at the moment, and I'm enjoying doing it, whereas before I never used to do it as much.
"I hope it will help me in the car this year. I certainly feel a lot better for it, and even if it doesn't make me any faster, I feel more happier in life than I've ever been."
Results are naturally crucial, and after the team finished a high of sixth in the constructors' and Di Resta performed admirably in the second half of the campaign when he scored 25 of his 27 points in the final nine races, the pressure is on for improvement.
"We punched above our weight last year, and to overtake a world championship-winning team like Lotus (formerly Renault, who finished fifth last season) will be a huge task, but everybody's spirits are high," added Di Resta.
"Personally I set myself a platform with my performance over the second half of the season, and I know I have to build on that at the start of this season."
Di Resta will be partnered by Nico Hulkenberg after the team opted to dispense with the services of Adrian Sutil, the younger German stepping up from his role as test driver last year.
For Hulkenberg, the forthcoming campaign represents a new start to his F1 career after previously driving with Williams in 2010, only to lose his seat last year to pay-driver Pastor Maldonado.
"Last year wasn't easy for me, but Force India have given me a chance to prove myself," said Hulkenberg
"I've kept myself sharp and now I'm back. Now, ahead of my second year in F1, I want to establish myself."
The latest Force India sported a new nose, in line with the latest regulations, with a hammerhead-shaped piece at its tip.
To date, Force India, Caterham, Ferrari and McLaren have all offered their own interpretation of the regulation.
Di Resta said: "I saw that nose in September last year when the car was in the tunnel and I thought 'oh, that's a bit different'.
"I actually don't think it looks that bad. I'm quite keen on it, and it blends with the car quite well.
"Obviously, in our tunnel, it's telling us that's the best way to extract the downforce. At the end of the day it's performance and how fast the car goes that really matters."
