Home Block Pulls Advice (and where to find cheap weights?)

Howdy,

I'm trying to get my fingers stronger faster. As of right now I just do some hangboarding before my gym sessions 2-4 times per week as part of like an expanded warmup/workout pre-climbing. The gym is a bit out of the way for me (and not open convenient hours) so I'm trying to get some finger training in my dorm. 

I have a metolius light rail, but I'm scared that I'll peel a doorframe off if I used a pullup bar with it. I also have a tension block that I would like to use for some pulls but I genuinely don't have enough weight in my house to get a challenging 8-12 second rep on a 20mm single hand edge. I put every book I own in a bag and it only gets strenuous at like 8mm. Does anyone know how I can get cheap weights to use at my dorm? I've been checking fb market and craigslist but weights seem really expensive. I'm thinking maybe water jugs or sand or something could work, but I dont want to like break a bag and mess up my dorm carpet. does anyone know any solutions?

if the tension block idea does end up working out, what are people's thoughts on doing 3 days of gym climbing, and doing pulls like 2-3 days in addition? Will i risk blowing up a pulley or will that be good for my strength?

LMK if anyone has thoughts or recommendations. thank you for the help!

The biggest risk to your pulley is your very first sentence. 

With fingers, "stronger, faster" is almost an oxymoron.

You can build muscle relatively quickly but connective tissue builds very slowly. So the faster you build muscle, the more likely you are to overpower connective tissue and create long term damage.

_**You really can't go fast with connective tissue! **_  

You'll have to do research about the specifics of how fast the connective tissues can adapt. You're young so you're probably on the faster side. Proper rest and nutrition will be critical for optimal speed.

What you're wanting to do is the easy half: muscle growth. _Do not overdo this! You will blow a pulley or worse!_

But you can work on muscular strength. Very likely you current connective tissue can handle a 10% gain in strength, just be careful.

A super cheap pull setup is a bathroom scale on top of a short piece of 2x12 with an eyebolt that sticks up above the scale where you clip your sling and pull block. It's a poor man's Tindeq.  Just stand on the scale, pull, then subtract your weight.

You will prevent some injuries if you consistently incorporate extensor and rotation strength exercises.    If your trying to maximize the speed of gains, this is critical.

But, to say it again.  If you maximize strength you will out-pace connective tissue and do permanent damage.  Normalize to a max pull over 1-2 months.  Don't attempt to increase.  Then try to increase 2lbs/month for 6 months.  Then stop gains for 1-2 months.  This is a rapid gain protocol.  Even this is risky.  Go bigger and you'll regret it.

Totally a guess but would figure your school has a gym with machines.. take the block to the gym attach to pulley.. free with the cost of tuition

bucket + quickrete + bent rebar or metal pipe for a handle=homemade kettlebell
