>>3396869Starting strength is a routine designed to teach you all the major compound lifts, build a strength base and teach you how to build a lifting program for yourself. Essentially it's a good way for beginners to get into weightlifting, of any kind, strength or aesthetics. I assume you mean HIIT (high intensity interval training) too, which is not any better for fat loss than LISS (low intensity steady state) cardio. Also if you want to get thin like a catwalk model then just eat way less. If you want to actually look good, like an underwear model, you need to lift weights.
