Total body workouts are necessary in order for us to look and feel our best. Workouts focused on only cardio (running), or solely on strength training (weight lifting), are tremendously less effective than training programs that incorporate both cardiovascular and strength exercises. Benefits of aerobic exercise include reducing blood pressure, strengthening of respiratory muscles, lower stress, improved mental health, healthier circulation, better looking skin and more. Lifting weights is tremendous for your muscle development, healthy bones and looking like an athlete!
