( CNN ) '' Wait up 2015 CNN Fit Nation Team and Dr. Sanjay Gupta -- you want me to climb up Stone Mountain -- that is over 1,500 feet straight up . Are you nuts ? '' I screamed . Yes . This is actually what I signed up for when I uploaded my video to the CNN Fit Nation website in December . `` But climbing mountains on Sunday morning -- you got to be kidding me , '' I exclaimed . But it was all part of the process I realized I was going to take on as I learn how to be a triathlete . After our first initial week with a trainer and nutritionist , the six of us were introduced to a whole new way of how to approach fitness and how to incorporate it into our lives . I knew it was going to be a difficult task , especially for someone like me heavily involved in civic affairs and community service . At Lifetime Fitness , our nutritionist walked us through a number of exercises on how we should look at food , nutrition and our calorie intake . After being on several diets over my lifetime , what he said was simple . To look and review your intake and replace it with other foods such as fruit and vegetables -- these small steps can be major impact on your training . Tackling nutrition and calorie intake can also be exactly how I viewed the climb up Stone Mountain . I put these nutritional issues on the backburner for years . It was pretty much like looking at the mountain that I was about to climb that morning -- where do I start , where do I begin ? -- and telling myself that it was going to be an arduous task . My training schedule has also been an uphill battle . In January and the first weeks of February , I started strong with my gym , running and swim workouts . However , as life pressures got in the way , I saw myself withering off . But luckily I have been inspired by my 2015 CNN Fit Nation teammates to keep me on track . Their updates have been truly inspiring and have helped me think about the struggles I face in my training activities . As I get older , I realize that fitness and nutrition are key to long-term health ; however , the support of friends and family is also important to help tackle your health . My team members of the CNN Fit Nation have been there for me . I recently weighed myself when I visited the doctor 's office . It has been six weeks since I hit the scale . I actually lost 20 pounds . What ! Really ! Uphill battles are hard to see when you are in the middle of them . But you keep moving . Just like that Sunday afternoon in January , I could not wait to be on the mountaintop and see the view from Stone Mountain with the members of 2015 CNN Fit Nation . And guess what ? After all this huffing and puffing over the last six weeks , I ca n't wait to see the view in September at the Malibu triathlon . It 's just another uphill mountain to climb .
George `` Chip '' Greenidge Jr. says training schedule has been an uphill battle . The former NFL player and coach said he was told by the team that his contract would not be renewed after this season.
