Hailey Bieber Ditches Pilates for Weighted Vest Strength Training

This summer, Hailey Bieber, who is a model, entrepreneur, and mother, has transitioned her fitness regimen from Pilates to strength training with a weighted vest. In a recent Instagram post to her 58 million followers, she showcased herself wearing a weighted vest and glute bands on each thigh. The use of weighted vests is known to boost muscle development, enhance bone density, increase calorie expenditure, and improve cardiovascular health. Since her pregnancy in 2024, Bieber has been working with personal trainer Kirsty Godso, who also trains Kaia Gerber and posts strength training content online. The bands she used seem to be blood flow restriction bands, which aid in faster muscle growth. Additionally, Bieber maintains her Pilates and hiking practices for a balanced fitness routine.
