Basically you can break the rowing exercise up into three stages.  Each of these three stages,  exercise different muscle groups whilst you are performing the different mechanics of the rowing stroke.

 How much effort you put into each stage determines how much benefit you will get from the exercise. This also gives you the potential in this part of the stroke to concentrate on the core stabilisation group.

The second stage of the rowing machine exercise is primarily focussed on core stabilisation for positioning and power. It therefore should come as no surprise that the major muscle groups worked here are your abdominals and lower back ,  with your quads, hamstrings,  and gluts still playing a part.

This is easily verified by doing a vigorous rowing machine workout and feeling the abs and lower back getting really well exercised. You will feel the effects of this exercise very rapidly after starting your workout.

Translated into the real world, flabby tummy,  poor posture, your thighs and that saggy, dimply butt,  can quite easily be a thing of the past by exercising on a  rowing machine. Best of all, rowing machines these days are relatively cheap and compact.

This puts you in a position to buy your own and use it at home without breaking the bank. No more parking at the gym or fighting for the next available ergo when you have your own indoor rowing machine.

As with the first stage of the indoor rowing machine exercise, you really need to know how to perform the exercise correctly. Bad technique severely diminishes your potential benefit, but also you can risk injury.

Don’t get left behind in the fitness stakes and go with a really solid workout routine. A rowing machine routine is well proven to give you a very good cardio vascular workout.
