Do you want to go catch a movie tonight ?   I can't , I have to go to the gym .   Come on ! You can go tomorrow , just skip it today . It's not as if you are gonna get in trouble !   Actually I will ! I am working out with a personal trainer that gets on my case if I don't go . I like it , because it makes me feel more obligated to go and get healthy .   That's cool , does your personal trainer basically teach you how to work out ?   Yeah . He makes a work put plan depending on the areas I want to work on , or the muscles I want to build . Like for example in order to get better muscle tone in my abs , pecs and biceps , he makes me work out with free weights . Then for my quads , calves and hamstrings , I do leg lifts or squats .
