i got myself some bands called bodylastics pity, they are really really good the tension you can make with them is massive and they come with some really useful attachments for curls or straps to go round your wrists or ankles and also a door anchor so you can have the bands secured to a door frame from either the bottom, top or even the side. they are a great product i use them if i am going to be going away and will have no access to a gym and they really helped me recover after my op last year. just a thought google bodylastics and see what you think. great work on your workouts mate keep it up
