A switch

Took a break tonight from the gym.  Instead, put on my swimming attire and visited the pool.  My cardio was working well the past 8 days in the way I managed to swim for almost nonstop (except a few seconds when I had to wash my goggles to remove the fog) in 40 minutes!!  I felt my lung is getting stronger as breathing was going well.  My arms are tired now but seems like the muscles are a bit tightened!!  Yes!!! Go!! Oscar!! Go!!
