I guess you make summer what it is for you...when the temperatures drop to where you need a jacket and it consistently stays that way, otherwise, it's still summer for me. Maybe that's how we treat taking care of ourselves too. Keep delaying the regimen we once were on with exercise because it's not going to make a difference or have a negative affect on the body. The body renews itself on a daily basis and just as the seasons go through a preparation from summer to fall with the change of temperature, we must help our bodies prepare too. It does start mentally seeing ourselves coming back into that regimen. However, just as the body compensates where it needs to, we can compensate between the choice of enjoying our workouts of what's left of the beautiful days of summer and getting back to your indoor regimen. You will do your body good in the long run...until we can do it again next summer.
