Hydration advice online swings between “sip occasionally” and “carry a jerry can.” After coaching people through Indian summers and AC offices, I prefer ranges plus feedback loops.

A practical starting target

Body weightApprox. 35 ml/kg
60 kg~2.1 L
70 kg~2.5 L
80 kg~2.8 L

Increase when training hard, sweating outdoors, or eating a lot of salty food. Medical conditions (heart, kidney) may need individualized fluid limits — that is clinician territory.

Training days

  • Start the session hydrated, not chugging mid-set only.
  • Sip during longer workouts.
  • Replace fluids after heavy sweat sessions.

Myths

  • Water alone does not create a fat-loss deficit.
  • You do not need to hurt yourself forcing water.
  • Food moisture (dal, fruits, curd) counts toward fluid status.

Key takeaways

  • Use ml/kg as a start, then adjust.
  • Watch thirst, urine color, performance.
  • Heat and training increase needs.
