How to say "stamina" in Japanese

• 体力たいりょくJLPT N1approx.Common
  nounCovers stamina as bodily capacity: the physical strength and endurance needed for sport, hard work, or a tiring day. The natural choice when 'stamina' refers to fitness and the body's reserves.
  体力たいりょくを維持いじするにはちゃんと食たべなければいけません。↗

  You must eat properly to keep up your strength.
• スタミナCommon
  nounThe loanword, used much like English 'stamina': the energy to keep going through sport, work, or a long day. It overlaps with 体力, leaning toward pep and resistance to fatigue.
• エネルギーJLPT N3approx.Common
  nounPrimarily 'energy' — electricity, fuel, or a person's vitality and drive. 'Stamina' does appear among its senses, but for physical staying power this is seldom the word you want; it is really 'energy'.
  僕ぼくはエネルギーを使い果つかいはたした。↗

  I have exhausted my energy.

Choose 体力 for stamina as physical strength and endurance, 「スタミナ」 for staying power and pep in sport or daily life, and 「エネルギー」 only when you really mean 'energy' — it rarely covers stamina.
