How much weight should I use on the 5/5/10 Dumbbell Press Multi-ROM?(How much percent of max?)(My max overhead standing is 135lbs)
63.45%
I’m kidding, It’s impossible to answer as it varies from person to person. You should hit technical failure or close to it as the end of the set. Pick a weight that allows you to do that. It might require some experimentation at first but from there you’ll have a good idea.
