棒铃的好处还不止上文所说的多平面运动、抓力强化等， 下面3个益处有些高分词汇，我都标出出来了

7. Kinesthetic Training （/ˌkɪnəˈsθɛtɪk/ adj. 动觉的;运动觉的）动觉训练

Kinesthetic training is essentially training for body awareness, i.e. balance and coordination.

Due to the offset weight of a steel club, steel club exercises are very similar to unilateral training. Unilateral training (like split squats, lunges, one arm presses) is essential for increasing balance, coordination and core stability. 

By performing a single arm exercise with a steel club, you are combining unilateral training and offset training, which is like a double whammy （一箭双雕）for improving balance, coordination and core stability.

The steel club will greatly improve sports performance as most sports require exceptional balance and coordination. This is why you see a lot of unilateral training in athletic programs, and a big reason the athletic community is taking to the steel club like no other.

8. Core Stability （核心部位的稳定性）through Anti-Rotational （防旋转）Exercises  通过防旋转练习塑造核心部位的稳定性

This benefit essentially goes hand in hand with kinesthetic training. By training for balance and coordination, you are increasing core stability. Core stability is best trained through anti-rotational exercises. Powerful core stability will allow you to take force from one side while maintaining balance. Football, basketball and soccer players will greatly understand the importance of this.

BONUS Benfit: Steel clubs are a much-needed change of pace

赠送的益处：棒铃带来急需的节奏变化

It’s always good to try something new in life, it’s even better when that new thing is proven to be effective and it’s a lot of fun. Steel clubs release our inner warrior and innate being. They are also therapeutic （/ˌθerəˈpjuːtɪk/ adj. 有助治疗的）and meditative （/ˈmedɪtətɪv/ adj. 有冥想特点的）in a sense （在某种意义上）. This may seem like a pseudo-benefit （假的益处）, but you should never underestimate （v.t.低估） fun.
