In short, yes. You’ll most likely want to get a power tower-designed dip station though. The reason is that you can attach bands to the pull-up bars, or give yourself some assistance with the dips. For less assistance, once you get closer to doing a full bodyweight dip, you can attach the band to the dip handles. Keep at it, and you’ll get there. Negative or controlled eccentric reps have helped many people in their effort to do a bodyweight dip, too.
