No, it doesn't. If your goal is to build a bigger, stronger back, it isn't going to matter.
mmm i was doing 50kg (3 sets of 10) with pullups (palm facing me) but when i tried palms facing the other way i couldn't lift that haha
The best part is that the EMG studes have actually been done (although there are problems with such studies) that show the different emphasis placed on different muscles, but overall the same muscles are being used. But something tells me you dont have the ability to research them, and you would obviously interpret them incorrectly.
Why is it that some people have such an easier time with chin ups rather than pull ups if its all the same muscles? Just from my own experience, I find chin ups easier so that's why I've been focusing on wide grip pull ups
It puts the bicep in a much stronger postition. Which is going to be the main muscle difference as the bicep isnt activated very well unless it is fully supinated. But as far as your back is concerned hand position changed very little. Just make progress at whatever movment you choose to do.
I do overhand on my back day because it concentrates more of the work on your lats and I do underhand on arm day because it concentrates more on your bi's. So it matters what you want to work. Back overhand arms underhand, while both grips will work both these muscles the concentration of which muscle is taking the most heat changes from grip to grip. Just like doing a wide grip bench press or a narrow grip bench press, wide does chest narrow does tri's.
I hope the original poster got the message that it's not going to matter. Do both, do one, do mixed. Just get stronger at them and eat more calories than you burn.
Who started this pullup = pronated and chinup = supinated crap?
This must have began in the late 90s or something because I have about 6 bodybuilding books produced in the 80s which use the terms pretty interchangeably.
If anyone's interested, I will find and scan pages which show it being called 'chins' or 'chinups' when people are using an overhand grip.
Even browsing Google Books I found a good example of this:
This image is from a 1952 manual by the US army on physical reconditioning which can be freely read here:
I'm sure there are numerous other examples. Chinning has included overhand grips for a long time. The move to exclude overhand grips and call them 'pull ups' is a new movement, and one that seems incredibly lame.
Here's a book from 1884 (which you can also get for free at http://books.google.ca/books?id=dKACAAAAYAAJ&num=16 ) which uses the term "pulling up" (obvious predecessor to pull-up) to describe underhand grips:
Why is it a 'silly' technicality?
I can feel a difference ----- as a lot of people have already mentioned palms out (pullup) is much more back/lat ordeal. Palms facing you (chinup) hits biceps/ lats.
A better question is "What is the difference between a Romanian Deadlift and a Straight leg Deadlift?"
Not much difference in level of lat engagement. The main difference is that pronated puts the elbow flexors in a much weaker position, as well as puts the lats in a less effective position. It's more challenging not because it's a better exercise, but because it's less natural, anatomically.
I would do both. Each are unique movements that will hit the body differently.
Do them both for complete back & bicep development.
I do both, they are just great.
It is a trick question...
Neutral is the best. Overhand = weakest position = your back most likely won't fatigue first. Underhand = stronger position, so you are giving your back a better chance to fatigue first. Neutral = strongest position for your biceps and forearms = back gets the most work through the ability to do more "work".
Romanian shouldn't even be called a deadlift, it should be called a Vladlift, after Nicu Vlad, the Romanian who popularized the lift. It begins at the top, with the eccentric, so it's not a dead lift. It's an undead lift.
Maybe that limits the peak contraction or something but I find it feels great since you can pull as hard as you want without moving (like added isometric resistance) since the grips stop you from going up further.
I've trained solely on overhand chin ups (pull ups) for a while so overhand is way easier for me. I've noticed that doing underhand chin ups now really stresses my wrists and shoulders. I'm thinking that it is a shoulder girdle flexibility issue from only doing pull ups for years. To hold the horizontal bar, my arms and shoulders have to rotate inwards for chin ups and it is very uncomfortable. Does anybody else have that pain?
