These days Gunna is a new man in two ways.

First, he resurrected his rap career and didn't get taken down by the snitch claims after copping a plea in the YSL case. 

Two, he's gotten a whole new physique and slimmed down considerably.

The 30-year-old showed off some of his workout routine not too long ago and was complimented on his new, healthier lifestyle. 

But Gunna said it wasn't cardio or weights that changed his appearance, it was engaging in constant bedroom activity.

TMZ caught up with him in Beverly Hills and asked how he got so slim.

"Lifting legs," said Gunna before getting into a vehicle.

Any response to his answer?
