RE: Redefining Fitness.

... costs and the potential social discomfort of public workouts.

Yes, I also came to the conclusion that in the end it is simply to expensive to go to a fitness studio.

I reduced the complexity of my workouts significantly.

I do the same: I alternate between jogging, swimming and a cardio program and in addition focus on doing the exercises squats, sit-ups, planks and push ups (when I played tennis some time ago I noticed I really should also focus on the power of my arms) regularly. If then I still have time I do some other stuff, but if there is no time or energy left for that, it's no problem.

To anchor my progress, I adopted a personal reward system.

My reward is eating pizza, especially as I am so hungry after swimming always, hehe.
Actually, since my last vacation, when I visited my family in the Philippines, I gained some weight as I am a real food lover, but most important for me is to have enough stamina and strength again now.
