1. Weightlifting
I said "...have a good strength training program. You don’t need a gym membership — but it’s easier to use weights than gravity, especially with core muscles.
I made a comment about lifting weights being a "cop out." A cop out, only in the sense that it is not a complete work out. I probably could have phrased this better.
I bench 300 lbs (max), squat 400, and deadlift 500 -- lifting weight has been a key part of my strength training program -- problem is, strength training is more than just lifting weights.
For example, instead of doing squats/leg press , or lunges, try running the steepest hill you can find 10x at full-sprint --30-60 seconds.
2. 90 min/ day
This comment was meant to suggest block 90 minutes out of your schedule to work out. Not work out for 90 minutes. If you drive/ride/walk/run to the gym, that takes time. If you stretch, that takes time. If you need to make a protein shake after you workout, that takes time.
3. Get in Shape
The overarching idea hear is simple: physical fitness, however you define it, is important. I wrote this post to share my own challenges in getting back in shape, and to encourage those who aren't currently in shape to try it out.
Really, regardless of whether you want to lift, run, bike, swim, et. al, the idea is to pick something and do it-- make a decision to get in shape, and go do that activity.
The decision is more important than the specifics, at least in the beginning.
