Stephanie Sanzo Celebrates Birthday With Brutal Leg Day Workout
Social media fitness influencer and inspirational personal trainer, Stephanie Sanzo took to Instagram to share her post-birthday workout, proving that you really can put off daddy time.
The Australian beauty, who earned the nickname “StephFitMum,” for how she got back into shape after having children, invited her 3.3 million IG followers to a virtual party at her gym, where she gave leg day some serious love. “Thank you everyone for the birthday wishes,” he wrote, explaining that although his birthday may have been on April 3, the workout will be in session 24 hours later. “This is my first workout at 39 years old,” revealed Sanzo, before pumping some serious iron.
Stephanie Sanzo’s Post-Birthday Leg Workout
- Barbell Back Squats: 4 Sets x 6 Reps
- Leg Press Machine: 4 Sets x 12 Reps
- Hip Thrust Machine: 5 Sets of 12, 10, 8, 6, and 12 Reps
- Kneeling Cable Bent-Knee Kickbacks Positioned with Standing Dumbbell Hip Abduction: 3 sets x 15 repetitions of each exercise
Why This Leg Workout Builds Muscle Fast
The buff beauty welcomed her new age with the same intensity that made her a popular powerhouse in the first place, taking four heavy sets to encourage growth in her quads, hamstrings, and glutes with barbell back squats. Sanzo does a deep squat to really feel the stretch, before sitting on the leg press.
The leg press, like the squat, is a triple exercise that requires movement from the hip, knee, and ankle joints, and is a great way to continue to work out the quads, glutes, hamstrings, and calves, because the machine puts less stress on the spine than free weight barbell squats, providing support and control to avoid overuse injuries.
The third was the hip thrust machine, consisting of 5 sets with varying degrees of repetition. Sanzo started with 12 repetitions and dropped by 2 repetitions in each set, until he reached 6. But for his fifth and final set, he went all out with 12 more repetitions to force muscle hypertrophy and gain more. Sanzo then capped off his strong leg day with a great double finisher, opting to set up two cable trials. Part A was a kneeling cable.
To do this, the brown bomb headed towards the cable station and knelt on the chair, using the rest of his back for support. As Sanzo reversed Dad’s timing, he hit the glutes, hamstrings, calves, and spine. In part B, the fitness trainer stood up from a side position in a cable station, abducting a standing dumbbell hip, to shape the outer hips while taxing his thighs.
“Looks amazing as always,” wrote one impressed fan. “I’ve been following you for years. Your consistency is truly inspiring,” commented another fan. “May this be the best year ever my queen,” wrote another.
M&F Hers I can’t wait to see what your next year looks like, Stephanie!
