There is no magic pill, no magic body wrap, and no magic supplement that will ever replace hard work and discipline in the gym and at the dinner table. Yes, vitamins, pre-workout supplements, and post-workout supplements are incredibly important (especially if they’re the correct ones that support your goals); however, they still don’t replace the work.
Please, don’t be fooled by what you read and see on the internet; especially via YouTube. This is a business world and people are always going to try and persuade you to try something new. That’s perfectly ok; that’s how you discover new things. But again, that will never replace hard work. Stay focused, remember your goals and conquer them!
