Viaradaxx Ginkgo Biloba - This herbs helps concentration. Which may be helpful with a people that the gym has who can't keep up with their sets (slacking off). I never ever tried ginkgo myself but I've have been told by so people who it works, and business that it only brings on the painful throbbing headache. If you have trouble focusing in relation to your workout in the gym, test it.
