@curiousmel IME I've had some good shoulder/lat/trap growth and a small amount of chest growth. I don't think "looking odd" will happen but adding in some dips isn't a bad idea.
@broncofan No need. I always used an old granny walker that's surprisingly sturdy.
And recently I moved to an apartment that has three balconies. Each one has iron handrails with corners at both sides, and they're perfect for dips.
