Hi everyone, I only seem able to do muscle ups on specific bars. Metal bars seem very hard as the grip is slippery. However I can do 6-7 in a row on a bar which is dry and grippy. Any suggestions or tips on doing muscle ups on any bar??

Get used to it. Train in metal bars without gloves if you can, if not, train on metal bars with gloves so that you get used to it. After a while you'll be able to do muscle ups there. Good luck!
