 [ Symptoms ] my menstral cycle takes 30 days i had sex with my bf on 13th day is there any possibility that am pregnant [ Disease ] i am sorry to hear about your injury that is no fun unfortunately there is no straight answer to your question lifting weights has to do with fitness level not age i know 55 year old women who can bench press over 100 pounds and i know 30 year old women who can barely lift a 5 pound dumbbell if the ability to lift up to 50 pounds is a requirement of your job i suggest you ask your doctor about physical therapy to help increase your upper body strength without injuring your back or after you have been cleared by a doctor to return to normal duty you could consider increasing your fitness level by working out on your own be sure to start slowly and gradually build up your strength and endurance webmd has a great exercise workout and fitness center that can help you get started just remember always get your doctor is permission before starting any exercise program hope this helps
