In the tone arms in six weeks, it does not specify the amount of weights to use. Can you tell me?

Work your way up. Start with a weight that you’re comfortable with, then increase slightly after you feel that your current weight is too easy/light for you. Don’t strain yourself. Just go with the flow and build the weights as you get more comfortable with them. For example, if you start week 1 with 5 lbs, stay with 5 lbs until you dont find 5 lbs challenging, then week 3 or 4 (or whenever you are comfortable) try increased weights like 7 lbs or 8 lbs, and move up from there :) In the beginning, try 3 times a week to start, or whatever you feel comfortable with, also make sure you have a rest day for your arms between each arm work out.
