<s>[INST] I AM 65 YEARS OLD,I HAD ANGEOPLASTY FOUR WEEKS AGO AND A STENT IS PLACED,AFTER ONE WEEK I STARTED MY WALK AND NOW I AM DOING 4 KILOMETERS WALK EVERY DAY FINE AND EASY, MY QUESTION IS WHEN CAN I START MY,PULLUPS,PUSHUPS AND OTHER EXERSICES WITHOUT WEIGHT. AND HOW MUCH CAN I DO...THANKS [/INST] Hello, If the angioplasty procedure was uneventful, the heart function is normal and there are no left untreated blocks, you may start doing your workouts right away as it's already a month since the procedure . Another scientific way to decide is to get a Stress test done and based on how you perform there and what workload you are able to reach, a call on what kind of exercise can do safely can be made. Hoping I could help.  Regards Chat Doctor.  </s>
