Best Pre-Workout: ProBar Fruition

Our top flavor pick: Strawberry

Bar Stats: 160 calories, 3g protein, 4g fiber, 21g sugar, 2g fat (0g saturated)

Pros: With flavors reminiscent of a slightly sweet Fig Newton, these organic bars deliver a blast of slow-digest carbs gleaned mainly from a mix of dried fruits, chia seeds, and rolled oats. Sugars are a little higher than our benchmark, but we've made an exception because studies show that carbs (plus a little bit of protein) before a workout give exercisers an energy edge, allowing them to workout longer and do more reps.

Cons: A little bit plain Jane in taste.
