Frequently asked questions about the KaakMaster™ Pro jaw trainer

Which resistance level should I start with?
If you are new to jaw training, begin with the 13 kg (28.7 lb) level to build a foundation. Move up to 18 kg (39.7 lb) as your muscles adapt, and choose 22 kg (48.5 lb) once you want maximum intensity. The TITAN bundle includes all resistances so you can progress at your own pace.

How long until I see results?
Results vary by individual, but with consistent daily training most users notice a firmer, more defined jawline over several weeks. Steady, regular use matters more than long sessions.

Yes. The KaakMaster™ Pro is made from food-safe silicone and is easy to clean, so it stays hygienic with regular use.

Yes. It is compact enough to fit in your pocket and comes with a neck cord and storage case, so you can train at home, at work, or while traveling.
