Beta-alanine, which will help delay exercise-induced muscle fatigue*
L-theanine, an amino acid that helps a way of calm alertness
So a stim-free pre-workout can nonetheless present advantages. However science has discovered that caffeine is the equal of Superman within the Justice League of pre-workout substances: The others are highly effective on their very own, however one is indisputably the glue of the operation.
“At BODi, we really feel that caffeine is a crucial a part of a pre-workout formulation,” says Falcone. “Its advantages, when it comes to serving to enhance endurance and efficiency, are supported by many years of analysis.”*
That’s why Beachbody Efficiency Energize accommodates 100 milligrams of caffeine, in addition to quercetin and beta-alanine, to assist present a lift of power and enhance efficiency.*

Beachbody Efficiency Energize accommodates 100 milligrams of caffeine sourced from inexperienced tea and occasional bean extract, which is in regards to the quantity of caffeine in a cup of espresso. “We selected that quantity as a result of a whole lot of analysis helps that dose for train efficiency advantages,” says Falcone.
These advantages don’t simply embrace power. Research counsel that taking caffeine earlier than a exercise can have cognitive advantages, together with elevated focus and sharper response time.*
