It had been around 8 years since i had been back to the Santa Monica stairs and i always loved making this part of my weekly workout routine. I remember working out on my own and with clients and without a doubt each and every one of us felt it the next day, as i did this time..
It is so good to mix up your workouts, your mind and body will respond in such a positive way.
Of course if you have injuries/restrictions that only allow certain exercise options you should always stay within those boundaries, but if that is not the case try stepping out of your comfort zone once in a while.
Here are a few suggestions... Find a hill in your area that you can walk up and down, give yourself a length of time to do this for or on shorter hills pick a number for how many times you will do this... On the treadmill you can play with your grade/incline to challenge yourself...Find some stairs in your neighborhood to climb... walk at a slightly faster pace....the list is endless, but please stay hydrated, listen to your body and if you have any discomfort, fatigue or dizziness stop and rest, Remember tomorrow is another day.
