Shake-weights seem to be everywhere these days, probably due to their incredibly awkward commercial. The question on everyone’s mind is does it work? The answer is yes…kinda.
The Shake-weight is a 2 lbs weight with springs on each side. While using the shake-weight may yield minor results at first, it is still only a 2 lbs weight and your body will get used to it and no longer benefit from its use.
The general consensuses on the internet is that it will give the user a minor muscular gain (not as much as using actual dumb bells) until your body adapts to it. After your body adapts its just like doing the exact same routine without benefiting from it.
