Good to know

Would it be good to invest on those wrist weights?? the type where you can strap on and off {adjustable weights} when doing normal day to day activity then? I was actually thinking of getting a pair for the wrist and for the ankles..

What about things like aerobic exercises? Would that be helpful in anyway?

Sorry I'm not sure what does the Acronym F and J's stand for... could you please clarify that? Much appreciated

Thanks!
