In addition to all the bootcamps, spin classes and high-intensity workouts, I enjoy yoga… regular, hot, hot with weights…and now yoga with cardio!
I added yoga to my workout routine a couple of years ago, and it has greatly improved my flexibility, muscle recovery and mental awareness. Yoga is great for the mind, body and spirit, and I feel that it adds perspective and balance in life. So much can be obtained from just one or two yoga classes per week. I highly recommend it…whatever level and temperature you like!
Here’s my favorite…
Radiant Hot Yoga
I enjoy hot yoga, especially with weights (yoga sculpt). Be warned, it’s hot!…around 104 degrees, so if you can stand the heat, I highly recommend it as alternative way to sweat-out a workout! Be prepared with plenty of ice water, absorbent yoga mat and towels.
My favorite hot yoga studios is Radiant Hot Yoga, a “non-Bikram” style of hot yoga “flow” that is very challenging, yet enjoyable.

I found a site that mentions an 88 year old Yoga instructor. It’s a commercial site advertising a green tea supplement, but there’s some value in it. HealthFirst site:

I just watched a great video clip on “down & up dog” for working the abs. Keep your arms straight and don’t move them as you bend up and down. To work the abs, keep your heels pointed directly towards the ceiling and don’t rock them in and out. Your butt and torso are the only body parts that goes up and down, and that really works the abs and core. Enjoy!
