Why Women Lift: Krystle


Personal Trainer, Singapore

Krystle is an ACE certified and a PTA Global certified personal trainer, and is also a certified AFPA Prenatal and Postnatal Fitness Specialist.

With a background in CrossFit and powerlifting, Krystle has been strength training for over five years. She is currently training with a bodybuilding/hypertrophic approach, as her current goals are mostly aesthetic ones, but she still love pushing for PRs and lifting heavy.

Most of her clients are women who mostly want to be “toned” – to lose fat and build muscle. She also works with new moms, who tend to struggle with body image and safe post-pregnancy workouts.

She hopes that each client will walk out of the gym learning something new each session, whether it’s a new movement or exercise, or a cue that guides them to lift better. She also hopes that her clients feel empowered and strong after each session!
