Think function and critical job demands when establishing sets and reps with post rehab and medical exercise program design. If the client’s critical job demands require walking the equivalent of a football field two to three times during his or her shift, two to three sets of 10-15 reps won’t prepare the client for return to work and certainly doesn’t give the client a chance for a successful outcome. 30-45 reps doesn’t give the client the necessary intensity to meet the critical job demands. Sets and reps take require a total of 150 to 200 reps might be closer to the demands placed on the client at work. Now we do not start the exercise program with 150 reps but we work toward that goal. Remember to recognize the need for sets and reps that mimic critical job demands. The concept of critical job demands applies to post rehab clients as well as industrial workers and athletes. So, are you preparing your client for a postive functional outcome when he or she returns to work?
