[|Human|] I was recently working out with a trainer for the first time. During the workout I felt fine. It was after the stretching that I felt my heart rate up and my arms tired and tingling. When walking to the car I felt a bit nauseous. I am still sore from the workout a couple days later, but are fine otherwise. Is this just from a lack of activity? I am 47, weigh 178 and have no health issues nor have had any. Last physical 2 years ago showed everything fine
[|AI|]  Hello, After going through your medical query I understand your concern and I would like to tell you that heart rate is ever-changing phenomenon depending on your physical activity, stress and physiological changes. After workout, you might have low blood sugar levels, and you felt a rapid heart rate, so it is recommended for you to have 2 digestive biscuits or a cup of juice before workouts. Hope I have answered your query. Let me know if I can assist you further.
