Go into any large gym today and you will find an enormous array of machines. There are a couple of machines for every single muscle group.

However, unless you are a bodybuilder really trying to perfect that sculpted physique, I really question the value of spending a lot of time working away on all these isolated exercises.

In many gyms it's quite rare to see anyone deadlifting - whether for fear of getting technique wrong, or maybe doing something silly - I really don't know.

If there is any single exercise that hits the largest amount of muscle groups in one hit - then the deadlift is it. It surely is one of the most powerful metabolic boosters there is. You can do heavy low-reps, or power through 15 rep sets that leave you gasping.

Of course getting the technique right is extremely important - BUT - we all have different shaped bodies and good technique on one person can look different on another person (it's to do with length of your back relative to leg length). Make sure you get a trainer to assist you with correct technique.
