Every bodybuilder and weight trainer will have his or her favorite exercises for each body part. That's how it should be - as you progress through the various stages of learning you'll understand what works best for you. It is useful, however, to take stock of your progress every so often and carry out an analysis of where you are and what changes, if any, are needed to move onwards and upwards.

Part of this analysis should include an assessment of the core exercises that make up your bodybuilding training program. In this article we'll look at the leg exercises that have proven their worth to serious bodybuilders for many years. Where appropriate a series of exercises suitable for achieving pre-exhaustion will be presented. All exercises should be performed to failure with one set of six to eight reps.

1. Leg extension - this exercise will allow you to isolate the thigh muscles preserving the strength of the other leg muscles for the compound exercise to follow.

- Push the pads until the knees are almost locked.

- Pause.

- Lower with control to the starting position.

2. Leg press - you can move straight on to this exercise if you are sufficiently experienced.

- Place your feet firmly at shoulder width on the foot board.

- Bend the legs until they are almost touching the chest.

- Pause.

- Return with control to the starting position.
