If working out with a barbell has always intrigued you, but you feel a little intimidated wielding a big stick with weights attached all by yourself, then you should definitely check out BodyPump [1]. These hour long classes are structured entirely around working all your major muscles, and then some, with a barbell and some hand weights thrown in for good measure.

Using differing weight amounts (the weights can be easily changed and lock onto the bar bell), you alternate between working the lower body, upper body and abs. Your entire body will get worked as you practice different lift techniques like dead lift, clean lift, and overhead press. All this can make you feel very tough, in a good way. Generally, one body part is worked for a full pop song and this can mean working your triceps for three and a half minutes. For me that was a seriously increased load on my triceps, since I generally do two sets of 12 a couple times a week. In light of the that please take heed of this suggestion:The first couple times you take the class, I highly suggest you go easy on the amounts of weight you choose. You should feel no need to keep up with the instructor, especially if you want to move your arms the next day (or two, or three).

If you want to see if there is a class near you check out this class locator [2]. Hopefully you're pumped up about pumping!
