In reply to Ava Adore:
Sorry for the late reply, had a stock take at work.
Frenchies are a power endurance pull up exercise. You pull up like normal, and lock off in the high position for say 3 to 5 seconds. Then you lower steadily down, and pull up to a 90 degree lock for 3-5 secs, then lower down and pull up to 120 degree lock for 3-5 secs. This is one repetition, then you start again. For power endurance you are aiming to carry out a set of repetitions that causes us to fail at about 1 or 2 minutes total, the point at which the body begins to be unable to process energy anaerobically anymore, and moves over to aerobic . If you were doing five second locks and aiming at failure at 1 minute then that would mean 3 frenchies.
I wouldn't start doing them until you are much stronger, you'll just get injured. They are very unforgiving and you need lots of rest. You really need to be thoroughly warmed up. It's best to be able to do say 15 - 18 pull ups no problems at all before you move on to more advanced exercises like this or your system will just get damaged.
Hi lo pull ups are simpler. I larks foot two slings from my bar, 60cm and 120cm. You can knot them to suit you for exact length. You do your a similar pull up regime to the one I described above, but with one hand on the bar and one in the sling which more closely mimics a climbing position - how often do you move from hands of equal height? If you need to use weight assist as before then do so to get the number of reps right.
Typewriters are when you have a wide grip on the bar, then keep your hands in place, pull up, move your body across to one hand, hold, then move across to the other hand, then back to the middle and back down for 1 rep. I find this mimics a trad climbing scenario looking for gear and holds. Again adjust weight to get the exercise to get 3 sets of 3 reps and build to 3 or 4 sets of 6 reps then adjust weight.
Try it, it works. I went from 6c to 7b+ in three months. Get some dedicated coaching as well, try using video at the wall and take a laptop down for instant review and you'll be able to see the holes in your technique and your physical weaknesses. Use a dedicated programme to work on these and you'll improve no end.

Neumann can be picked up well cheap second hand, and I used to have the older version of Horst which was useful.
