Almost everyone has heard of Slendertone, but do you know what it is, and what it can do for you?

Slendertone have been making abdominal toning equipment for over 30 years, and offer a range of different models depending on your gender, activity level, and the body part you want to work on - in addition to the original abs toner, you can get models that fit your butt, your thighs, or your upper arms.

All of their different products work on the principal that by repeatedly sending electrical impulses through the muscle it forces the muscle (stomach muscles, arms, etc) to contract multiple times. This constant contraction is what causes the muscle to tone and tighten.

Their products come with a 30-day toning plan that includes 'warm up' and 'cool down' phases, and a range of variable settings - most have around 7 toning programmes and up to 99 intensity levels. You control these settings with a convenient handheld control unit, and can use it while sitting at home watching TV.

For those who want to work out, there are also active models, which include features like a heart rate monitor and a calorie counter.
