P90X vs. Crossfit: Which to Choose?

and Crossfit each have pros, cons, and some similarities, but differ mainly in how they are performed. P90X consists of a series of DVDs and can be performed at home. These types of home workouts are ideal for many people who don’t have time to go to the gym or aren’t comfortable working out around others.

P90X is an intense workout and can definitely be effective, as is the case with any high-intensity workout that last for 60 minutes or more. The keys to this DVD set are consistency from day to day, its focus on the large muscle groups, and the included nutrition plan.

I would caution (just as the P90X program does) that if you’re not used to working out at an intense level, then it’s best to try another type of workout and build up to P90X. As always, stay hydrated and stop working out if you feel faint.

I like what P90X has done by bringing intensity to home workouts.  Insanity, another home workout series, is also very intense. The difference between P90X and Insanity is that P90X works best with some equipment such as dumbbells and a pull-up bar whereas Insanity requires little along the lines of extra equipment.  I give P90X an “A” for home workouts, and program completeness.  It has great variety and hits all of the major muscle groups and exercise types.

Crossfit is also a very intense workout, but it is usually performed in a group setting at a Crossfit-designated location (gym, gutted garage, or otherwise). My favorite aspects of Crossfit are the high levels of intensity, the group environment, use of non-standard equipment (ropes, large tractor tires, etc.), and the inclusion of power movements (cleans, jerks, snatches, deadlifts).

Crossfit’s use of these power movements can also be a critique, however. Due to their complex nature and the risk of injury if performed incorrectly, power movements should be taught by certified weight lifting experts. Although Crossfit loads for power exercises are not near maximal, they frequently include very high numbers of repetitions – a no-no for power movements.

Additionally, Crossfit classes (both effectiveness and safety) are highly dependent on the quality and aptitude of the instructor. In the group setting with a good instructor, Crossfit can be a great workout to augment your routine. Be careful if you decide to go the individual route by simply looking at the “workout of the day” (WOD) on the website. You risk injury without proper training and supervision.

For group workouts, I give Crossfit a “B-“. I would use it to augment my current workout, but the workouts from week to week lack exercises for each of the major muscle groups, namely the chest. Crossfit can also be pricey.

With both P90X and Crossfit, I caution against too many intense workouts without adequate rest.  Intensity is good, but consistency is better and rest is always important.
