HI Lisa -- glad to hear you're getting back to exercise after your challenging couple of months. Other muscles to focus on during strengthening besides the lats, would be your mid and low trapezius -- and yes, this workout is safe for that. Keep thinking 'shoulders down your back'.... not necessarily needing to aggressively pull them down, rather, give a thought to your shoulder blades being a bit heavy on your back while having a sense of lightness in your front body/chest. Good luck!
Except for the fact that my shoulders griped and complained endlessly during the handweight section, I had a good time taking the class. Though the ladies sure made it look easy. I am definitely taking more light handweight classes and this one again! Thanks Amy:)
