Pilates is not a thing, it is a series of exercises that do not need *any* equipment. Mat exercises can be done on a towel or just your living room carpet. Most pilates focuses on the core area but there are definately moves that work the arms. You can look these up online or there are dvd's you can buy for about $10 or under if you want to view it.
Another option is just doing regular dumbell arm workouts with soup cans. You can also do standing pushups if you lean against a wall and push away, do this with hands shoulder width apart, then hands together and then index fingers together and thumbs together forming a diamond to work different parts of your arm and chest muscles.
