Well, today’s workout is one you should probably get used to seeing on here – The 2×20.

The 2×20 is one of the primary building blocks of your fitness, and is a great default workout. Short on time? Not sure what to do? Do one of these.

So, what the heck is it?

Pretty simply, the 2×20 looks like this:

– Warm up.

– Go as hard as you can for 20 minutes.

– Recover for 2 minutes.

– Go again for another 20 minutes.

That’s the basic version. Success on this is,  however,  all in the details.

The idea here is to go as hard as you can for the duration of both intervals without being forced to go easier at the end of the second interval.  If you run out of gas before you finish the second interval, you went to hard. If your vision isn’t blurry at the end of the second interval, you went too easy.

If you’re doing this with a powermeter, you want your wattage output to be as close to constant as possible. We’re talking 10 watt variance at the most. Keep it steady.

These take practice to do well, and the better you get, the harder they get. This is another workout that works great on the trainer, and that’s how I do ’em, which is a good thing… because I always wind up flat on my back on the floor trying not to puke after the 2nd interval.

I’m really not kidding about the seeing spots thing. If you can learn to push through your limits when you do these, you will get better and you will get better fast.

(…but, yeah, it will hurt.)

(…a lot.)

(…but, you know, the good kind of hurt…)
