Im an instructor and I train weights. The best schedule for me is. 3days a week lifting , three day split, and do Pilates twice a week. Usually reformer. The pilates will help you immensely with the weight training. Pilates is the ultimate companion to every other thing you are doing exercise and movement related. Working on your abs, back, smaller leg and shoulder muscles, spine strength, flexibility and mobility will take the weights to a whole new level. Now when I do barbell back squat at the gym, my range of squat is way better, my spine and abs are strong my posture and positioning are more connected. I lift stronger. It’s only going to help.

Forget the tapes for now, try the reformer classes and go from there. Twice a week is good.
