I go to the gym 5 days per week with 1 day break after 2 consecutive days of going to the gym.

I work a different group of muscles each day. I don't work the belly, but I've been told to hold it in as hard as I can and exhale while doing the other exercises and it works that way.

  • I do 3 sets for 4 different muscles, but for the same part of the body (e.g. Legs) and after I finish those I do around 2 more exercises for stuff like biceps/triceps/shoulders.

  • 10-20 minutes on treadmill (I was told to not walk a longer period of time, but do a faster speed, so I speed it up more when I get used to the previous one)

  • Protein + carb shake and small break

At this point I hit around 2 hours

  • Hit dry sauna for 10-20 minutes and a bit in a humid one too

At 17 (BMI is 27), do you think this is a good enough routine or could I be doing more? I also ask if I should drop the treadmill in favor of some swimming? The place I go at has a really nice olympic pool that I sometimes swin in.
