Whilst certainly small enough to fit in a larger size gym bag, you'd be better off making a sling from an unused jeans belt to carry on your shoulder simply because this is not lightweight.
It's a beast of a thing, made to last and although it didn't come with any literature stating a weight limit, I'd be happy using it to lever a fully laden bus off the ground.
Very ergonomic, very easy to use, built to last indefinitely regardless of the abuse it is given, it is very stable in use and is of course very easy to use so it represents fantastic value.
All I need to do now is etch it with my name in case I accidentally leave it at the gym because I'd be devastated to lose this.
