INTENT!

I'm training in the gym today and an overweight woman starts training next to me by doing seated dumbbell bicep curls and then seated shoulder lateral raises with a good rest between sets. What is her goal, her intent??? If she wants to lose weight/fat she needs to train so much differently, she's wasting her time. She needs to get as much energy out of her body as possible, and seated exercises with long rest periods is not the right way to go about it.

Focus on your intent during your sessions!
