A man's jawline transformation has sparked debate and raised questions about the effectiveness of jaw exercises. The viral video, which shows the man's jawline becoming sharper over 80 days, has captivated millions. However, experts caution that the reality behind such before-and-after videos may be far from what viewers see.
The main muscle targeted in jaw exercises is the masseter, which is responsible for chewing. While repeated use can strengthen or activate these muscles, they are already utilized daily in activities like chewing, talking, and clenching. Dr. Michael Ormsbee warns that excessive jaw training could lead to soreness, headaches, tooth stress, or TMJ-type issues.
Physical therapist Lori Rubenstein Fazzio agrees, stating that jaw exercises could result in changes in jaw alignment and tracking, but are unlikely to change the shape of the jawbone in 80 days. She emphasizes that even orthodontic devices like maxillary expanders take time to show results, typically 6-12 months of constant pressure.
A case study analyzing the use of jaw exercisers found limited efficacy in reducing double chins, enhancing jawlines, and tightening faces and necks. Dr. Ormsbee advises against using these routines as a main strategy for changing facial shape.
The man's transformation, while impressive, may be a result of various factors, including genetics, bone structure, body fat, hydration, skin tightness, posture, lighting, and camera angle. Experts urge caution and recommend consulting professionals before engaging in such exercises to avoid potential risks and ensure safety.
