I recently did some heart tests because I was experiencing pain in my left arm. My doctor mentioned it was muscular pain. My ECG didn't come out normal, but the TMT and 2D echo were fine. I'm really confused about whether it's okay to do strength training at the gym. I've attached my reports. Can you check them out and let me know what you think?

based on the reports you have provided, it's good to hear that your TMT and 2D echo results are normal, despite the abnormal ECG. Since your doctor has mentioned that the left arm pain is muscular in nature, it is generally safe to engage in strength training at the gym. However, it is important to start slowly and gradually increase the intensity to avoid any strain on the muscles. You can start with light weights and focus on proper form and technique. Additionally, it would be beneficial to consult with a fitness trainer at the gym to create a suitable workout plan that aligns with your health status. Remember to listen to your body and stop any exercise that causes discomfort or pain.
