@Bigchick, toning your muscles means using the intended muscle areas extensively whether you're in the gym or not. If you depend on weights then you may not only limit the amount of time spent working out, but also the range of weights you can use is limited.
Besides, doing many repetitions with a small weight may end up being boring.
So what's left? I guess learning to be innovative with how you use your body in the normal day to day activities is the best thing. It's much like remembering how to play and using play to promote fitness.
Dance to your favorite songs for ten minutes, do wall pushups while waiting for your sufuria to fill with water...
Maybe your most flabby muscles are in the triceps and belly. So before standing up from your seat you do an exercise called 'dips' for the arms. And leg lifts while you're in bed. Just haba haba...
Sometimes you just take off with husbands phone if applicable. Wacha akukimbize up the stairs. Akikupata try some wrestling na umwambie hakuna striking. But unaeza mkalia if necessary. Mtu akitap game imeisha.
