Creativity is key. I don’t throw out the baby with the bath-water because some machines people hate or don’t think are safe for anyone frankly can be safe and effective IF DONE PROPERLY. Example…the leg extension machines with the foot too far behind the knees–dangerous…change the range of motion and it is not only safe for many but recommended by orthopedic surgeons and physical therapists. The Smith Machine…most I see on it use it improperly and even dangerously while others use it in an ineffective manner. Although I primarily stay away from machines of any kind, there are times when the machines can be handy and can add variety.
