what exercise should i do to remove my bat wings?

Answer 1

Standing with your arms straight down at your sides, flex the muscles in the back of your arms. Simply bend your arm at your elbow and keep the muscles tight, raising and lowering. When you lower, make sure your arms stop at a position slightly behind your back. This tightens the muscles in the back of your arms without expensive equipment purchases.

Answer 2

You should do reverse tricep curls. They definitely help with the bat wings. I suggest investing in some inexspensive weights.
