For the weight lifters and the body builders, isolation of the muscles

or separate body parts workout training is prone to injury. Complex
movements versus isolated body areas by performing single or multi
joint exercises for injury resistant and strong body is most talked
about and controversial subject nowadays.

According to the experts, our body fails to respond or work due to
the isolation of various parts during a training program. The strength
and good working of the body depends upon kinetic chain movement.
A complex movement is basically one of the normal functions of the
body when large areas aid and support other areas of the body to
complete a movement during an exercise or workout. Human body has
thousands of muscles that are linked and intertwined with each other.
It is next to impossible to differentiate and isolate certain muscles. In
reality, muscle isolation does not exist because all the muscles in that
area assist the particular muscles in the area.

If we compare muscle isolation or single-joint training to multi-joint
complex movement we come to know some interesting facts. Single-
joint movement is more prone to injury as well as it makes the body
less or non-functional. As compared to that multi-joint complex
movement strengthens the whole body making it injury resistant. It
transforms the whole body not only a particular functional unit of the
body.

There are many side effects associated to muscle isolation that are
rather damaging the body such as joint problems, excessive fat
storage and tendonitis. On the contrary, multi-joint movements
assist in having more powerful and functional body with no extra
fats, muscular problems and of course resistance to injuries. (more…)
