Michael,
The snug back straps are perfect.
I like a tight fit. I have 4 or 5 sets of the AMF and Lyons handles and have wrapped them with tape and resorted to using a sticky golf glove to get the desired tightness, but who wants to use a glove in warm weather.
I just ordered the 2 1/2 pound weights.
I have done Heavyhands walking since Dr. Schwartz wrote his book.
Your handles take it to a more productive and enjoyable level.
Dr. Schwartz would have loved them.
They are worth their weight in gold.
