We all have two types of muscle fibre – slow-twitch and fast-twitch. Understanding how each of these works, is the key to ensuring a workout that will really get results.

• Slow-twitch muscle fibres support endurance activities like walking, swimming and cycling. These fibres are always stimulated first during exercise. They contract slowly so they can keep moving for a long time without getting tired.
• Fast-twitch fibres support quick, powerful movements, like jumping or sprinting. They contract quickly, consume a lot of energy (in other words – they burn fat!) and deliver the strength and power you need to spring into action.

To improve your overall strength, fitness and body tone, it’s important to flex both types of muscle fibre. EMS specifically targets those harder to reach fast-twitch fibres, boosting the effects of your workout.
