Query: A good buy

I have had the steel bow for about 6 weeks now. It has helped me loose weight and my muscles are firmer. I no longer have back pain. Also it has encouraged my 6 year old daughter to exercise as well which is a good thing.I don't believe this device will increase your strength as effectively as lifting weights would, nor do a full body workout like weights would - but it is portable and quick and will make you fitter and stronger than you would if you did nothing. Which is important to me as I travel frequently. Definitely worth buying.Also it is much cheaper than weights or a home gym. And it can fit easily in a closet so not taking up much space in your homeI also use the larger bullworker - both compliment each other as some exercises are more effective with the larger device and some are more effective with the smaller device.
