Is there any good energy drinks recommended for working out ?

Every time I finish a work out I get really tired and exhausted and my body feels to give up even during the working out. And after I feel so weak my arms and legs feel so heavy and like there's no life in them. And Im going to start the insanity workout from Sean t and I know it hard I already did it once and it's hard as hell. What energy drink is there that will help me keep my enerygy up and recover better. And if someone can give an in depth explanation on the electrolytes and all that stuff ! Thank you
