It's absolutely fine to drink Gatorade for deferred times of action. The electrolytes empower you to recoup stuff you lose while sweating and the extra sugar gives you a respectable shock of vitality. Since you say you're practicing for four hours consistently, it's okay to drink Gatorade step by step. Just be careful drinking it outside of diversions since it has a mind blowing 56 grams of sugar for each container, which could provoke weight gain.

I used to get ready for four hours step by step as well, and I brought two Gatorade bottles + 2L of water to sharpen.
