My favorite Tracie workouts are:
-Leaning Out
--this one has a mix of traditional and functional strength training. It flows really well and has great music. There's also a 7 minute cardio segment you can skip.
-The Firm Maximum Body Shaping. Another
--45 minute no nonsense, get in and get out strength workout
-Focus Breakthrough: 33 minute workout utilizing the weighted ball. Lots of fun!
-Better Burn Better Buns
-Defined Lines--has a little bit of everything. 4 limb work, ball work, and exercises utilizing the gliding discs.
-Defining Shape--Great strength workout that hits everything in just under 50 minutes. It also has a nice balance segment.
I also like Firm Tortoise, Step Forward and Back Up. Step Forward is a cardio step/lower body endurance step workout, and Back Up is a cardio plus strength workout. It has a really fun sports influenced cardio segment (using the weighted ball), and an innovative functional strength segment using light weights to work the small muscles of the shoulders and back. As you can see, most of my favorites are from the Longevities. Her Firm workouts are also great too.
Of the Reboots, I've only tried the first one. It's okay, but a little choppy. The cardio segments get in the way in it IMHO. But it's still good. I have yet to try the second Reboot, the Stronger Longers, and her new Studio Series.
All I'm all, I'm a huge Tracie fan.
