Hey, I seriously think I am fat, Although my classmates say I am not, I think they are just being supportive friends! Anyways this is what I am doing, Sit in a straight-backed chair with armrests with your feet flat on the floor. Place your hands on the armrests and do a push up with your arms. Hold for a count of six. Then slowly lower yourself into the chair and relax. Repeat this strengthening exercise ten times. I REALLY hope this helps you, enjoy. :D
