Health concerns are minimal for you in 2017, Gemini, but be sure to do a health examination early in the year, around January or February, to make sure everything is in order. You may need to make alterations to your diet by adding a bit more fiber, and you may also want to rededicate yourself to exercise early in the year.
You like exercise, but you get bored easily, and therefore, you have difficulty sticking with the program. Try something that will keep your interest, like Circuit Training or Boot Camp. Exercise that constantly challenges you is ideal.
