Question: what do you do to get rid of fat arms??

Start doing real strength training, lots of squats, deadlifts, lunges, presses overhead, bench presses, pull ups and variations for beginners, etc. These exercises build muscle on your whole body, and get you very lean quickly. There is no such thing as getting fat off of your arms without getting it off your whole body as well. Think of the fat on your body like the water in the tub. There is no getting water out of one part of the tub exclusively. Once you pull the plug, the water level of the entire tub goes down, not just the part of the tub nearest the drain. So the bigger your drain, the faster your tub goes down. Likewise, the bigger your exercise, the faster your bodyfat content goes down. Your biggest exercises are squats, deadlifts, cleans and snatches, presses and pulls, and all types of unilateral and bilateral variations with different implements such as sandbags, dumbbells, barbells, kettlebells, etc. Things as simple as pushing a car or running up a hill can be done by anyone, anywhere, anytime. But we find excuses why not to do them as opposed to just getting it done. Now go do it. If you do not know how to do it, come see me, I'll show you how.
