Many thanks for the message. Indeed, I realy am not too sure I am doing it right at all now!! Will cut down the repetitions for sure and hope to find someone who can guide me personally too, which would be reassuring.
I will be posting again - in the last week or so I have felt a slight ache in my mid/lower back and I cannot help connect it to the 5T's, perhaps particulalrly #4. I do suffer from lower back problems anyway. Could I be doing myself more damage???
