I would suggest you start with the passive stick exercise and add one additional exercise each day hopefully building up to the whole program at the end of the month. Check in how that feels and give your body a day to say yes or no to that exercise. Take the time to listen to the response and give yourself an opportunity to integrate the movement and the new postural placement . With tendon injuries they can be slow to recover and grading your load is important. If in doubt show your manual therapist and check that this is appropriate for you.
The workout in this program is something I take my clients through in stages and I always double-check with their therapists to make sure that there is nothing else that would interfere with the pacing of the program. eg surgeries or an autoimmune condition that would slow down the healing stages.
