- Comfort and Fit. A belt or pad that stays secure during movement is crucial. Consider size: some belts are one-size-fits-all while others have adjustable straps for different waist sizes.
- Program Variety. Multiple programs (e.g., warm-up, toning, recovery) allow you to customize your EMS session. Devices with at least 5 programs offer versatility for different goals.
- Safety Features. Look for FDA clearance or evidence of safety standards. Automatic shut-off and adjustable timer ensure you don't overuse the device, which can lead to muscle fatigue.
