The Total Flex is an all in one style exercise machine that uses bungees as resistance. It folds down to practically nothing (in fact my husband put it away and I couldn't find it) but does all the same workouts as effectively as a huge home gym. Because of the way you can add resistance by using more of the cords (and purchase more if you want) I find it a good workout, but so does my much stronger husband. It had mixed reviews. Same maker as the H2O mop or something, so you're not buying a super high quality machine, but for what it is, well worth the $249. Great for cramped spaces, minimal assembly, some good add-ons you can get if you want, and workout suggestions and instructions on how to target areas using the machine.
