Yes for heavy weight lifting, I'm a semi competitive power lifter (ok so I've only done three sanctioned competitions so far ) where I took 2 fourth places in benching and 1 third for dead lifting. I do say, there is something quite satisfying about breaking your previous maximum repetition. I like to see older guys at the gym who have been lifting a long time, so much to learn from them. Do share your knowledge when weightlifting questions come up!

Swimming, not so much, I'm a better sinker than swimmer.
