Workout noobie here, I am 19 and I am 6’0 but only 130 pounds so I’m trying to use this quarantine to my advantage to eat more and make my arms bigger. I have dumbbells that I usually do tricep and bicep workouts with. I know how many sets and reps give my body a challenge, but how do I know when to stop my workout? Is there such thing as too much working out that can lead to consequences? I usually cycle through different methods I use with the dumbbells and I usually go an hour/45 minutes and stop. Is that too short? Does it depend on your body ie case by case?
