  3. 3Move with control through a comfortable full range of motion.
  4. 4Return slowly to the starting position and keep tension for the next repetition.

Tips & tricks

  • Start light and add load only when every repetition looks consistent.
  • Keep your core active and avoid unnecessary movement outside the working joints.
  • Stop if pain replaces normal muscular effort.

Common mistakes

  • Starting too heavy and relying on momentum.
  • Dropping the return phase instead of controlling it.
  • Losing position as fatigue increases.
