Ask HN: CrossFit or Not?

It probably depends on the group you choose. Try a couple if you don't click with the first one.

The emphasis really is on the "cross." I was a fat slug (and I am once again, I got sick). They were good folk and they let me do what I wanted and what I could. I was amazed after a few months what I could do.

I don't think it makes sense to do one or two things exclusively, we have a lot of muscles that do complicated things. Crossfit makes sense and it worked for me.

In the end it's a tool like anything else. This tool requires the user to commit to learning how to use it and then the necessary practice to realize the benefits. You can do this on your own or under the instruction of someone else. I came from a triathlon background but decided I was over the long periods of training. I tried CrossFit and haven't looked back. I enjoy the variation and yes, I enjoy the competition aspect of it.

If you devote enough time to CrossFit and work hard, you will end up in peak physical condition, just like Greg Glassman, the founder of CrossFit:

I recommend starting with a favorite CrossFit exercise: kipping pull-ups. They're a great way to rid yourself of unwanted arm mobility.

After you've gotten your elbows in top shape with kipping pull-ups, I recommend focusing on the CrossFit kettlebell swing (AKA American swing, not to be confused with the hard-style swing). This exercise is so cutting edge that it has yet to be recommended by any competitive kettlebell lifters (girevoy sport) or their coaches. Interestingly, some of these aforementioned people are critical of the CrossFit swing, but I assume this is because they're Russians and Easter Europeans who lack an appreciation for the kind of think-outside-the-box innovation that comes natural to American entrepreneurs such as Glassman.

A program like CrossFit only works if you stick with it for a decent amount of time. If you stick with it, you will see significant gains in endurance, strength, and overall fitness. I would definitely recommend at least trying out the CrossFit gym nearest you and seeing how it goes.

My experience was very positive. However, the instructor I had was also my martial arts instructor who is very good natural teacher. I have heard the quality of a CrossFit instructor can vary a lot.

Try it out, but don't buy into any faddish aspect and don't overdo it.

depends on what you're looking for. If it will get you into the gym and nothing else will, go for it. If you don't have the interest or discipline to go on your own, go for it.

If you'd like to see maximal strength/muscle gains, go see a powerlifting/olympic lifting coach for a few sessions (or join their likely weekly program for not very much $$) and do a linear progression program like Greyskull, Starting Strength, etc.

"but what about my core?" Guess what? After years of squatting on medicine balls packed to the ceiling, I can't say I had a strong core. Squat 2+x your body weight and you'll be surprised how magically strong your core gets :-)

My advice is similar to jsonmez.

If you are trying to lose weight, I would mainly focus on weight training. I would also add in walking, swimming, running, or biking.

Diet wise: more protein rich food, more fruits and veggies, and cut out high-fructose corn syrup/high sugar products. Eating healthy is just as important as the exercise itself.

It is a scam. Just lift weights and do cardio. 8-12 reps 3 sets. Eat right. Don't buy into fitness fads. :)
