Ultimate Test Max   Let's face it, doing heavy flyes in a strict and disciplined manner is painful. When relatively heavy dumbells are lowered with outstretched arms until they're horizontal and even with your head on the bench, there's a searing kind of stress throughout the chest region. When you squeeze the muscles as you carefully arc the dumbells upward and back together, the pain and positive effect from working the pecs so directly is only intensified. This is a good indication that you're doing them correctly.
