What's your bodyfat percentage?

[ono]

Your probably skinny/fat then Miles, that means you don't weigh much. But your body fat percentage is high or higher than it should be for your weight. Or your not carrying much muscle.

Easiest way to cure this, is put on a bit of weight while doing weight training so basically bulking up. When you feel you've seen some good gains. Then do a cut thats what most people do mate.

What do you mean when you say do a cut, Ice?

Tone up medium weight with dumbbells ETC, do more cardio, eat healthly/dieting ETC.

Toning up has nothing to do with the weight of the dumbbell being used. Toning up is a direct result of stripping away body-fat to bring out muscle tone. So providing the person doesn't have much body fat, muscle tone will be on show. If the person lifts heavier weights and eats and recovers properly, providing he has maintained a low body fat level, he is likely to have more muscle 'tone' than a person who has just lifted 'medium' dumbbells as he should have gained more muscle. The lower weight, higher rep myth is just that....a myth.
