DAVID KIRSCH IN A NEW YORK MINUTE

You may have heard me use the term “Sexy, Sinewy Muscles.” It’s one of many Kirschian principles, and one that I use when working with my clients here at the Madison Square Club. 



Sexy, Sinewy Muscles come from exercises that shape and tone rather than bulk you up or neglect your jiggly parts. My exercise philosophy is simple: Do those specific moves that focus on the smaller muscle fibers of each muscle group, using a light pair of weights, and complete a high number of reps — 15 or more. 



This makes all the difference between forming the bulky muscles of a football player and the long, firm muscles of a dancer.

All of my cardio-sculpting exercises couple low-weight, high-repetition resistance with cardiovascular training . To get the Sexy, Sinewy Muscles you were born to have, I recommend doing a 60-minute session, or 45 minutes at the least. Do this 3-4 times a week. You’ll simultaneously increase your heart and metabolic rate, burn calories and fat, and strengthen your muscles without the bulk!
