Hi everyone I haven't read all of the way back through this post but my tip is try and make exercise incidental to your other activities eg I park the car at the other end of my local shopping centre so i have to walk up and back, used to ride my bike to and from work, saved $$, stress reliever etc etc.
Rachel that Aqua class sounds gross! Ew.
I am impressed with your weight loading.
I am still a beginner, warm up 5kg, squats lunges and back 10kg, triceps and biceps 5kg.
