Not to say "soft skinned hand", at the very least to make the hand much more appealing. Further, i don't feel comfortable having rough patches on my hand. There's no need to sacrifice appeal to gain strength, your statement seems to suggest having calluses all over the body would be totally acceptable since it would mean you're superbly strong, though it could all boils down to individual preferences.

I disagree with your statement that gloves won't not make much of a different. I previously used the machines without gloves and i developed slight calluses on the upper part of my palm but with gloves on, it doesn't even appear.

The calluses makes your skin rougher, making it having a better grip. Sure, you can keep you smoothed skinned arm but what's the purpose of being strong if you can't lift something heavy outside the gym because you don't ware any glove. And if you somehow decide to lift without glove, you'll tore your skin arm. But well, nvm it's your arm you can do whatever you want thou.

It's not got pig skin, it uses pigskin. The answer is yes. I brought this up with the folks at Ego Nutritions & they confirmed this. But I dunno whether all of their models are made of pigskin. I just ask Ego Nutritions to put up a clear signage for the benefit of their Muslim customers.
