Don’t drink water during excersize, it fucks your electrolyte balance. Wait till your at rest. People hurt themselves by drowning their insides with water quicker than their body can balance it. Personal anecdote from bartending: if I drink more than a swig of water mid shift my energy drops and my mind gets fuzzy. Personal anecdote from biking across the country: every time I drank more than a swig of water I started hating life, whereas when I didn’t I felt durable and enjoyed the ride. Long story short you don’t need water as much as you think you do while your active.
