I'm not trying to get below 8% I'm trying to cut weight for a specific sport. I have abs and can clearly see them. But just because your 8% doesn't mean you see abs. People carry their weight differently. Everyone's body is unique. Example Michael phelps. Since he's a swimmer his body adapts to being more buoyant in water so he naturally carries more body fat. 12 percent compared to sprinters about 7 to 10.
At 12% you're not seeing great ab definition Lol at 8 you better be pretty damn ripped. Anyway just calculate tdee, adjust carbs if you carry a lot of water, be in a deficit and call it a day. Simple.
