Flavor and Mixability Matter to Me
Since these drinks don’t have calories, the flavor sometimes can be bitter or artificial. I look for products with good reviews on taste and mixability so I actually enjoy drinking them before my workouts.
Transparency and Brand Trust
I prefer brands that clearly list their ingredients and dosages, so I know exactly what I’m putting into my body. It also helps if the brand has third-party testing or positive customer feedback for quality and safety.
Price and Serving Size
Some zero calorie pre workouts can be pricey, so I consider how many servings I’m getting per container. I try to find a balance between quality and affordability, so I’m not overspending but still getting effective ingredients.
How I Use Zero Calorie Pre Workout
For best results, I take my pre workout about 20-30 minutes before training. This timing helps me feel energized right when I start my routine without any crash afterward.
