I too have been the "strongest" on my day 1s. I know this has something to do with some of my endurance stuff I have done for years. My biking, hiking, rowing, and running background suits day 1. My traditional high school sports experience played a role in this too I'm sure. Anyways, my day 2 and most definitely day 3 workouts with regards to performance have suffered because of my background. It amuses me now, how I thought I was strong going into SimpleFit (I had been doing Bodybuilding type workouts since before my teens) but I quickly realized I did not have a lot of true strength. SimpleFit is sure fixing this. SimpleFit has been great so far because even with my background my muscle/aerobic endurance I know has improved along with my strength. Goes to show what day 1 anaerobic exercise can do. Why did I use to separate cardio and strength exercises? Can someone slap me please!
