i'm 18 and very overweight, and haven't regularly done physical activity for 2 years or so. but today i've decided i need to do something about my weight. however, i don't have the time, money or opportunity to join a gym or go swimming, so am trying to do what i can at home, which makes things more difficult. i'm looking at using the nhs 10 minute workouts, but i'm so clueless i don't really understand all the exercises. today, i'm 87.4kg and hate myself. what are the best ways to exercise at home with very little equipment? and how do you stay motivated (because losing weight doesn't seem to be enough for me)?
