Lot Description

The FitBoutique Booty Builder Hip Thrust Machine is designed for hip thrust exercises, including standard hip thrusts, wide-stance hip thrusts, and half thrusts, with optional resistance bands for progressive overload. These movements primarily target the glutes, with secondary engagement of supporting muscle groups, offering a low-impact, high-intensity workout. Below are the primary muscle groups affected, based on hip thrust variations.

1. Lower Body (Legs, Hips):
   • Gluteus Maximus (Buttocks): The primary muscle targeted, responsible for hip extension during the upward thrust. Hip thrusts isolate the glutes more effectively than squats, with maximum activation at the top of the movement (full hip extension).
   • Gluteus Medius and Minimus (Side of Hips): Stabilise the pelvis and support lateral hip movement, especially in wide-stance hip thrusts or single-leg variations.
   • Hamstrings (Back of Thigh): Assist in hip extension, particularly during the eccentric (lowering) phase, with increased activation in half thrusts where the range of motion is limited.
   • Quadriceps (Front of Thigh): Provide minor support during the thrust, stabilising the knees, with slight engagement in wide-stance variations.
   • Adductors (Inner Thigh): Stabilise the legs, especially in wide-stance or banded thrusts, preventing knee collapse.
   • Engagement: Hip thrusts on the Booty Builder focus heavily on the glutes (60–70% of effort), with hamstrings and stabilisers contributing 20–30%.
2. Core (Torso):
   • Rectus Abdominis (Abs): Stabilises the torso to maintain a neutral spine during thrusts, preventing excessive arching.
   • Obliques (External and Internal): Engage to prevent lateral tilting of the pelvis, especially during single-leg or banded thrusts.
   • Transverse Abdominis: Provides deep core stability, bracing the spine against the resistance of bands or body weight.
   • Erector Spinae (Lower Back): Maintains spinal alignment, supporting the back against the padded rest during heavy lifts.
   • Engagement: Core muscles contribute 10–20% of effort, with greater demand when using heavier resistance or performing unilateral variations.
3. Upper Body (Arms, Shoulders, Back):
   • Trapezius and Rhomboids (Upper Back): Stabilise the shoulder blades, anchoring the upper back against the padded rest during thrusts.
   • Deltoids (Shoulders): Minimally engaged, stabilising the arms if resting on the bench or holding bands.
   • Forearm Muscles (Flexors and Extensors): Grip the bench edges or handles for stability, with minor activation.
   • Engagement: Upper body involvement is minimal (5–10%), primarily for stabilisation, as the focus remains on the lower body and core.
