Train with Dumbbell

正确的哑铃会让你在举起八到十二次时，感觉到肌肉酸痛。您会感觉到肌肉有点灼热感，并且无法再举起您的手。

大多数男生比起女生上半身的力量比较大，然而建议开始时使用较轻的哑铃，通常介于二到七公斤。

The right dumbbell weight for you will fatigue your muscles in eight to 12 reps — meaning you feel a burning sensation and feel like you can't lift your arm anymore.

 Men typically (although not always) have more upper-body strength than women, but should still start with relatively light dumbbells, usually between 2 to7 kg.
