This kettlebell routine offers powerful results. Try it 2-3 times per week for 4 weeks. It is a great break from your standard exercise program. Beware the poundage suggested by the author, however. Rather, choose a weight comfortable but challenging for you. Also, pay prticular attention to the kettlebell swing movement. It is a hip hinge movement, not an arm exercise. Most people do it wrong. PLEASE CONSULT YOUR DOCTOR BEFORE BEGINNING ANY EXERCISE PROGRAM.
