Well, its more a function of AVOIDING embarrassment which I guess is the purpose of my PUBLIC weigh-ins.
When I started back, I immediately started feeling positive again. Worked steadily to get my heart and lungs strong again and was shocked at how the weight just fell off.
And my skin got tight again.
BTW when you focus on getting your heart and lungs strong (I recommend using a HIIT program - watch this video) you will just naturally have better and better cardio workouts without even noticing. One day, you will wake up and discover you have become a beast (in terms of being fit).
I just turned 70 y/o back in August and am in peak fitness.
Note of caution...if you do try the HIIT routine, start slowly at your fitness level. It is easy to overdo it.
Your heart is your body's engine..and your lungs.
All your body responds to how it is conditioned.
The capillaries in your body are conditioned by your exercise...so is your brain.
Your vanity muscles are not in the fitness equation.
Big muscles may look great (i.e. vanity) but they aren't needed for survival.
Look at the muscles of rock climbers...they are highly toned and powerful...but they don't look like they are ready for a body building competition.
