Any tips on preparing for 75 Hard?

Don’t over think it. Just start. Plan your day the night before – what times you’ll workout, if you need to pack a gym bag to go to work, what you’ll eat, etc. For your meals – keep it simple. Always get a lean source of protein, complex carbs like sweet potato or rice and green veggies. (If you’re doing Keto or another diet you’ll need to plan according to that)
