I enjoy Surge Workout Fuel just before crossfit workouts. Is there any reason or could I get better fueling from Plazma? Thanks!
The two do share some similar ingredients, but Surge Workout Fuel has some extras that make it a bit more specialized for endurance-type work. So for straight metcons or stuff with a lot of rowing, for example, Surge Workout Fuel would be better suited. For more basic strength work (like testing your CF total or WODs with a lot of singles), Plazma would be ideal.
