Looking back at all of the natural alpha characters I've encountered in my life, a reoccurring theme I've noticed is that very few of them lifted weights. Even if they did, it was usually for a purpose like training for a sport or to actually enter a bodybuilding competition, not to look jacked. Why that is I'm not 100% sure but I believe it comes down to their inner confidence which they gained from growing up in a masculine household. Also, they probably naturally have high T which contributes to their confidence so they don't feel the need to look like an Adonis to attract women.
I bring this up because there's such a huge emphasis on lifting in this sub for the purpose of enhancing your aesthetic. The mindset goes something like this, 'you need to get jacked so the ladies think your haaawt'. Looks-money-status and all that. The mindset should be more 'challenge yourself physically and stay in shape'. The difference is in the former you're lifting to look good, in the latter it's to challenge and exert yourself because that's what brings out your masculinity, with looking good being a bi-product. Frankly, obsessing over how you look is gay. That's what women do.
Challenging yourself physically makes you feel like a man which is obviously good for your confidence and will also balance your hormones and keep you healthy. This doesn't mean you need to lift weights. I went surfing for the third time in my life recently here in the Philippines and battling the ocean on a board for 2 hours left me feeling exhilarated and tough. I'm guessing MMA, rock climbing, intense labor, playing hockey, etc would all have the same effect. I'm not saying lifting weights doesn't have this effect but you should be doing it for the right reasons.

I was one of these guys. I lifted for 15 years and was usually the most jacked out of all my friends but it didn't do a damn thing when it came to getting laid because many of the other pieces weren't in place.
I've been all of the world and North America in particular is overly obsessed with muscles but it's more the men that are obsessed than the women.
Go to battle in whatever way you choose and then take that masculine energy and flirt with girls. Show your sexual intent. Get rejected. Do it again. Eventually pussy will come.
