Resistance training during a calorie deficit helps preserve lean mass so more of the weight lost is fat. Muscle also supports a slightly higher resting calorie use. You don’t need a gym — bodyweight, bands, or dumbbells work. Two to three sessions per week covering major muscle groups is a reasonable starting point for most healthy adults. Combine training with adequate protein and a moderate deficit for the best body-composition outcome.

Key facts:

  • Preserves muscle in a deficit
  • 2–3 sessions/week is a start
  • Pairs with protein + moderate deficit
  • Supports long-term results
