For those interested in weight loss or improving fitness isolating small
exercises is not necessary. Not that performing isolation exercises is bad, but
there are better ways to spend your time in the gym if you don't have goals for
building specific muscles. The lunge lateral raise is a perfect way to include
lateral raises in your workout program without "wasting time" doing them
separately. Since you are using your large muscles for the lunge, the lateral
raise not only works your shoulders, isolating your medial deltoids but
increases the weight during your lunges in addition to challenging your balance
and coordination.
