What’s verified and what isn’t
- Height is solid: Sydney personally corrected the record to 5’3¾” on her official X account. This is the most authoritative source for her height.
- Weight and Measurements shift for roles: She revealed gaining over 30 pounds in 2025 and going up four pant sizes to portray boxing legend Christy Martin. And later leaning back down for another project. Treat any fixed weight/measurements you see online as snapshots at best.
- Bra size is not public: There is no credible, first-party confirmation. Sites listing exact numbers don’t cite verifiable sources. I’m not including them to keep this page accurate and respectful.
Recent body transformation (2025)
Preparing for the Christy Martin biopic, Sweeney trained three times a day (weights → kickboxing → weights) for about 3.5 months. Plus a higher-calorie diet to add muscle resulting in >30 lbs gained and a significant strength boost. She himself said she performed her own boxing sequences. After wrap, she reduced again for a new role.
Training And Wellness (how she stays fit)
- Combat sports foundation: Longstanding interest in MMA/kickboxing, which she’s discussed in multiple features. It is great for cardio as well as power.
- Role-specific periodization: For Christy, she used a split of AM weights as well as midday kickboxing and PM weights with diet to support muscle gain.
- General wellness: Interviews highlight balancing intense workouts with recovery and on-the-road routines like sleep and simple self-care.
Let me break through all measurements clearly to help you understand in simple way.
Height That Sydney corrected herself
As mentioned above that Sydney publicly corrected her listed height, writing that she is 5′3¾″ which is about 162 cm. That direct correction from her social account is the cleanest source we have for height.
Weight & body changes As per role-specific, not permanent
In 2025, Sweeney trained intensively and gained more than 30 pounds to portray Christy Martin. Reputable outlets W Magazine as well as ABC and E! News reported the timeline and training: morning and evening strength sessions plus long kickboxing workouts. After filming, she returned to a different conditioning program for subsequent projects. For your kind information, a single weight number is rarely a stable fact for working actors.
Training & routine hints from press coverage
Press features describe a mix of weights, boxing/kickboxing drills and calorie changes timed for the role. If you want to replicate the style of training not the exact program, you need to consult certified trainers. So, actors often work with professionals to safely gain/lose weight for roles.
