An exercise in futility(opinion article)

WE CAN ALWAYS tell what our gym mates hope to achieve by the exercises they perform, particularly those who do not have a systematic approach to strength training.
They either have no emphasis or are over-emphasising on one particular part of the body and this is one of the most common causes of what you could call an exercise in futility.
It is fine if you start your workout by hopping on the stationary bicycles, the treadmill or the stair-master because you need to warm up first before you handle the weights. -more

I agree of this....gym is invariably .Sometime,gym members who move from one machine to another randomly are also going about it the wrong way. In my suggestion,we no need go to gym room,we can just do our exercise at home or go for a jogging .It the best exercise for different rank people.
