Understanding 1RM

1RM stands for one-rep max, the maximum amount of weight you can lift for a single repetition. Knowing your 1RM helps you set appropriate training loads to maximize strength gains and fat loss.

Importance of Resistance Training

In fat loss and body recomposition, incorporating resistance training is essential. It helps preserve muscle mass while you lose fat, ensuring your body composition improves.

Calorie Cycling for Fat Loss

Calorie cycling can enhance fat loss while maintaining muscle. Adjusting your caloric intake based on training days can optimize your body's response to workouts.

Tips for Fat Loss & Body Recomposition

  1. Track your strength progress regularly for effective body recomposition.
  2. Focus on compound lifts to maximize muscle engagement and fat loss.
  3. Combine resistance training with proper nutrition for best results.
  4. Be patient—body recomposition takes time and consistency.
