4) Lat machine pulldowns.

This exercise aims to develop the width of the upper section of the lats. The motion one needs to execute it roughly the same as in the case of wide-grip chinups, namely:
The subject grips a bar hanging on the cable of the machine with a wide grip. He/she puls it downward until it reaches his/her chest or back of the neck (depending how he/she wants to work the lats) pausing for a moment he/she then slowly lets the bar pull back up keeping it under control all through the motion.
Extra considerations:
- you need to avoid laying back. This will involve the lower back too.
- because of the amount of weight that can be varied, this exercise is a good way for beginners to train until they’re strong enough for the chin-ups.
