Definitions

  • the present disclosure relates to a hip-up exercise apparatus.
  • hips improve his or her dressing style when users wear bottoms. Users do hip-up exercise to lift his or her hips up.
  • the hip-up exercise is an exercise program to intensively strengthen hip muscle tone and lift hips up.
  • hips become rounded by doing the hip-up exercise, legs look relatively long.
  • hip-up exercises include squat, a leg lift where legs are stretched and lifted up with knees and palms put on the floor, and a grasshopper posture.
  • hip-up exercises are free exercises without additional apparatuses. Free exercise may develop gluteus, which is a hip muscle, to lift hips up. However, users have difficulty in doing the hip-up exercise using one's own body and get easily exhausted even with a small amount of exercise.
