Dips are a fantastic way of improving the definition in your arms.
But be warned, they're not easy!
Dips are an extremely good all-round exercise.
They work the biceps, triceps, shoulders, lower back and abs.
STEP ONE
Position yourself between a set of parallel bars.
If the apparatus has foot rests, put your feet there.
Lift yourself so that both of your arms are straight.
Make sure your elbows are at your sides.
Bend your legs at the knee - but don't cross them.
STEP TWO
Lower your body down as far as possible. And do your best to keep your elbows as steady as possible.
STEP THREE
Pause for a moment and then push yourself back up to arm's length.
Do it until your elbows are straight again at the starting position.
Repeat these 10-15 times for one set.
Some machines will have a weight stack on them to aid you during the lift.
The more weight you have on, normally means an easier exercise!
