Ngl, I've noticed this at the gym especially with Latinas.
They do all kinds of shyt from deadlifts to squats to working a little on the heavy bag but you'll rarely catch them in a spin class or doing anything of note on the treadmill.
Sistas are usually pretty balanced. A little bit of cardio, some free weights and machine weights with stretching.
Pawgs the most consistent and varied between different kinds of cardio and weight routines.
Indian/Pakistani women are the WOAT at working out. That's why they look OK young but fall off a cliff with age. They don't even try. No weights, slow walk on the treadmill and elliptical. Not sure why they're almost anti-athletics.
I thought I was the only one that noticed these trends. LOL
As I live in the UK I can't say much about 'Latinas' (be they Euro, Mestizo, Mulatto, Afro, etc) as there aren't that many of them in the UK. However, It's more or less the same with the others. I'll elaborate on what I see different ethnicities of women do at the gym.
Black women (the few that do go to the gym) - Tend to be balanced between cardio and weight training. Their cardio tends to be using stairmasters, ellipticals and the treadmill. They tend to mainly use weight machines (but not the leg press), and sometimes they'll use free weights for deadlifts and squats but that's about it. It's also dependent on age and ethnicity (e.g. Jamaican, Nigerian, Ghanaian, etc).
White women - They are the most consistent and varied with their gym activities. They will do it all when it comes to cardio, callisthenics and weight training. All types of weight machines including leg press.
All types of free weights including bench press.
All types of callisthenics except for pull ups.
All types of cardio machines and workouts except for the ropes and heavy bag work (this applies to most women regardless of race. ethnicity, etc).
Of course, this also depends on age and ethnicity (e.g. Eastern Euro women tend to be more weights focused as they tend to go to the gym with their Eastern Euro boyfriends or husbands)
South Asian/Desi women - Their workout routines are usually trash. Hardly any weight training or callisthenics. Just cardio, mainly slow walks on the treadmill, the elliptical and maybe the bike machines now and then. However, there is one South Asian chick at my gym that properly works out. She does it all. I must note that she does have a personal trainer. She's cute too.
UK Mulattas - In between Black women and White women. Obviously. Yet I tend to see mulattas use the leg press machine more than black and white women. Weird.
