Calling Out Some of the Biggest Lies in the Fitness Industry with Diren Kartal

from Life With Danni Duncan · host Danni Duncan

The fitness industry is louder than ever. Scroll for five minutes and you’ll see someone telling you the only way to lose fat, what supplements you need, and what you should never eat… And yet somehow, one half of it contradicts the other half. So today I’m chatting with Diren Kartal, an online coach who’s built a huge following in the fitness space and isn’t afraid to call out the BS. We talk about the biggest lies in the industry, why they spread so easily, and how becoming a dad has changed the way he approaches coaching. Stick around to find out: > The biggest lie in the fitness industry that actually harms people > Why telling someone “you can do anything” isn’t always helpful > The problem with before and after photos in fitness marketing > Why supplements are pushed so aggressively online > Whether honesty is actually bad for business in the fitness industry > Why most new online coaches skip the part that actually makes them good at coaching > The difference between a good coach and a bad one > What becoming a dad changed for Diren personally and professionally > Whether AI will replace coaching in the future … and SO much more If you want more of Diren, you can follow him on IG @diren.kartal If you want to try Hyro, you can get 50% off your first subscription at www.drinkhyro.com/danniduncan You’ll also get a free welcome kit, flavour sample pack, free shipping and a 30-day money-back guarantee.
