By the way, during one of the Vinyasa (Plank / Chaturanga / Upward Dog / Downward Dog) sequences, Tony introduces a new stretch, which I really, really enjoyed: While in Downward Dog, take one hand and grab the opposite ankle:
After the warm-up, we go right into Crescent Pose and (after another Vinyasa) the Warrior sequence.
While in Warrior One, Tony demonstrates a way to square your hips by extending one arm straight out to the front. This also helps deepen the hip flexor stretch. Warrior Two follows, right after another Vinyasa sequence.
For some variety, we interrupt the Warrior sequence for Chair / Chair with a Twist.
And then back to Warrior One, Warrior Two, and Reverse Warrior. From there, we transition into Right Angle Pose:
Tony takes another little break and takes us through Three Slow Push-Ups (military style -- elbows in) and Side Arm Balances (a.k.a. Side Planks). And then we're back to the Vinyasa sequence. While in Downward Dog, we perform the "knee to forehead" move from Yoga X, but we also get "knee to the opposite elbow" and "knee to the same side elbow" thrown in for good measure.
And then, from Crescent Pose, we pop up into Warrior Three, do some Standing Splits, and bust out our very best Reverse Half-Moon and Half-Moon Poses.
Unlike Yoga X, there are no balance moves in Fountain of Youth (e.g., Crane, Tree, etc.), but I didn't miss them too much. Instead, Tony moves right into Standing Hamstring Stretches -- first with his arms folded behind knees(!) and then with his palms under and against the soles of his feet.
Two squat moves follow: Squat with a Forward Fold and a Wide-Legged Squat in which we rock from side to side, with hands at namaste.
Tony then has us do a couple of core exercises: 20 Slow Bicycle Crunches and a bunch of Slow Scissors (which, as far as I can tell, are identical to Fifer Scissors from Ab Ripper X, but with your head, shoulders and arms off the ground).
We also do some Torso Twist Holds that we know and love(?) from the Yoga Belly 7 sequence in Yoga X.
And then we finish up with some extensions and stretches, including Knee Circles, Happy Baby, Side Twists, and Seated Hamstring Stretches.
Tony adds some cross-legged variations of Side Twists and Seated Hamstring Stretches; both greatly enhance the stretches.
A quick Cat/Cow and Lateral Child's Pose later, we're done.
At the risk of sounding like a shill for Beachbody, I highly recommend Fountain of Youth for any P90Xer who's having a hard time fitting a weekly 92-minute Yoga X session into their already-jammed schedules. Even if Yoga X fits nicely into your workout calendar, Fountain of Youth makes for a great recovery session, and is a fine substitute for X Stretch.
