I'm Determined!

Hello all you good people. Ive been an athlete my whole life and love sports. These last 4-5 years have gone downhill and I know I must stop feeling sorry for myself. Im presently living in Hawaii but do not have use of a full kitchen. I do have a frig and microwave. Any helpful hints on getting started would be appreciated. Is it better to go to the gym and work out in morning before the day gets started or after work. 

Anyway best of luck to everyone and Im going to give this my best shot. 

Take Care,

Greg
