What Is The Hardest P90X Workout?

A couple of my friends and site visitors have sent me e-mails asking what one of the 12 P90X workouts do I think is the hardest. How about all of them. Some are more challenging then others. What I like most is that you really can't half ass any of them. Each exercise pushes you. It comes down to how you feel that day and where your intensity level is at.

Since I consider myself an expert in the P90X field. I decided to make a list from the hardest workout to the not as hard (not easiest) workout. My factors in deciding these are based on what is going through my mind when I pull the DVD out of the booklet and how sore I feel the next day.

1. Plyometrics- I have been doing P90X for almost a year now and Plyometrics still kills my legs. Of course this is the workout that does the most for me as I am a big skier/snowboarder and runner. My legs have never been in better shape. The next day my legs are on fire and my ass hurts from all the lunges and squats.
2. Chest And Back - Push Up, Pull Up, Push Up, Pull Up, Push Up, Pull Up, and then repeat. Really? Is that chain of events necessary. Tony Horton does not like us. With so much emphasis put on those muscles it really is a killer. My arms are on fire and veins are popping out. Guaranteed to be feeling it the next day. 
3. Back And Biceps - Pull Ups, Curls, Pull Up, Curls, Pull Up, Curls, and repeat. My arms are dead after doing this. Switching from the pull up bar to dumbbells and going at a quick pace always keep me on my toes.
4. Chest, Shoulders, And Triceps- Push Ups, Shoulder Press, Tricep Extensions for an hour. There are different varieties of those exercises. I have never finished this workout without feeling exhausted after it. My arms are destroyed when I am done.
5. Shoulders And Arms- Lots of shoulder presses and curls along with some tricep work. I struggle with this one because my right shoulder has a small injury I got when I was younger. It does feel good to stretch out those shoulder muscles even if I have to use a lighter weight. Do I need to say anything more about my arms getting a workout here? I think you get the point.
6. Legs And Back - This is one of my favorite workouts and I was debating about putting this higher. I kept it lower because it is working the upper and lower body. The workouts above focus on one or the other. With two different body parts being worked there is a lot of energy to crank out as many pull ups and lunges/squats as I can. This workout is the one that I do the most pull/chin ups on as it is the only exercise you are doing for the upper body. My legs, especially the calves, still feel tender the next day.
7. Yoga X - I never realized how much I would get out of doing Yoga until after I did it a couple times. The only weight involved is your body weight. All of the poses and balance postures put so much emphasis on those little in between muscles. The stretching really loosens me up. I have noticed a big difference in my softball and golf swing from doing Yoga. It sounds easy to do but when I am done I still break a sweat.
8. Kenpo X - This is more of a fun workout to me than anything. Lots of kicking and punching going on. When I started using weighted gloves it felt like a workout again. That little bit of extra weight makes a differnce when throwing punches as it now forces the core to work.
9. Core Synergistics - To be honest, I have only done this workout a couple of times. It's probably because it fell on the off weeks and I was too focused on the other workouts to enter it into my routine.  
10. Cardio X - Since I am big into running I never got around to doing this one except for the couple of times it feel into my recovery week. I remember it being good but to me I'd rather run for an hour because I know that the other workouts are going to be back the following week.
11. Ab Ripper X - I must be crazy right? Abs at #11. Ab Ripper is tough. I am not denying that. My take on it is that since it is right after the toughest workouts it makes it harder to do. The few times I did Ab Ripper without doing anything else made a big difference. I was able to complete the whole thing with no problem. I still felt the burn but not as much as if I was trying to do a ton of pull ups for an hour and then do abs.
12. X Stretch - This is a tamed down version of Yoga X. The workout is under an hour where Yoga is near an hour and a half. I like it but not as many balance poses.

This list could change at a moments notice as they are all pretty tough to do. I feel pretty confident about numbers 1-7. These workouts always kick my butt. Even after doing them each dozens of times I still "feel the burn" the next day. I guess its a good thing though because it tells me that P90X is not just a 90 day program as it is a lifestyle change about how to workout and get results. If one of these particular workouts decides to attack me then I will redo the list and award it the #1 position. In the mean time this is how its going to be.
