Hey Eric, this sounds fun. Speaking of that weight loss thing, I failed

did not get to my goal. Last 7 pounds have been really really tough. Where do I pay up?
Anywhere, here's another program that might be able to help out: the Recon Ron program. I've heard of better results from it compared to the Armstrong one, although it's less popular.
Here's the chart:

Here are the instructions:
- Each day Monday-Saturday, do the workout for the week you're on. Take Sunday off.
- The workout is 5 sets. The number of reps in each set is on the rows in the weeks column.
For example, if you're starting on week one, you'll do 6 pull-ups for the first set, take a short rest, then 5, rest, 5, rest, 4, rest, 3. Do that each day Monday to Saturday. Next week, your workout will be sets of 7, 6, 5, 4, 4, and so on.
Here are some inspiration and ideas to keep things interesting for you folks. Some are more about pull ups, but the basic skills they go over should carry over into chin ups.
These two are for rings (the part 2 video is very rings-oriented, so I left it out), but they got the basic ideas down for pull ups: activate your lats and pull down your shoulders first, and if you're having trouble getting in those last few reps, it's okay to use momentum to get to the top and slowly lower yourself. It's not cheating--it'll still help you progress.

Here are some videos on free hanging, not even doing pull ups or chin ups. Of course the skills are related though and if you work on these, they'll also help you progress.

Finally, once you're able to get your chin ups, you can start a workout based around them. Here's one created by some cool calisthenics guys on YouTube.

Some personal tips from me:
- Keeps your legs and core engaged rather than flailing them around. For chin ups, I like to tuck my knees into my chest; pull ups, arch back and try to kick my own butt. Reason being that the muscles throughout our whole bodies are meant to work together, and I like to get that chain going. Chin ups have a very closed, global flexion feeling, while pull ups go the opposite way.
- Keep your shoulders externally rotated, i.e., rotate at the shoulder so that your elbows face each other. Don't force them beyond what's comfortable, but just in general, a really big posture problem modern life gives us is internally rotated shoulders. You can see it very clearly on this guy and how his thumbs point toward each other instead of pointing forward when he stands naturally
- Loosen up your shoulder blades. Here are two good videos: https://www.youtube.com/watch?v=y4Wo095zPnc abd https://www.youtube.com/watch?v=hzozw2Aso3M
Also, since the title of the thread doesn't specify chin ups and we're on the topic of bars, I'd like to also propose dips and pull ups
