If you are passionate, you have likely heard of Hunter McIntyre. He won the Hyrox Championship of Fitness three times, and he trained aggressively for it in order to win. He said his training regimen consisted primarily of HIIT workouts that focus on increasing overall fitness, burning fat, and building muscle.

“People just put sh** up on the whiteboard, and then they do it, rather than having intention behind it,” McIntyre said hours after the Hyrox Championship of Fitness. “I build longer workouts so that I can understand pacing.”

Pacing is a discipline that pays dividends when you’re going for a max effort down the road, whether it be a casual basketball game with friends or a marathon. McIntyre recommended ditching suggested weights if those numbers don’t make sense: “It’s not going to make you a better athlete if you’re not a 405 deadlift athlete. I pick weights that I know that I can hold certain intensities and I can allow my body to adapt to.”

To teach that pacing, as well as to whip you into a better multi-sport athlete, McIntyre has selected some of his favorite (re: most painful) workouts from his “30 Hardest Workouts” Guide, which is available on his HAOS site, all of which will get you into shape. Sure, they might also make you cry a little, but no pain, no gain, right?

So what are you waiting for? Don your favorite home workout gear, and prepare yourself for the gun show. With effort and patience, your fitness goals for 2022 will bear fruit with these HIIT workouts.

WOD 15/12/9

Many WODs have come before, but this one is the D-Day for the genre. Go through the first half at 15 reps of both exercises, then 12, then nine. This half should be performed as a bodybuilding workout: Slowly, while focusing on each contraction. After your midpoint rest, blast through the second half with the same rep count as the first half but with a tempo of a CrossFit workout.

  1. Deadlift (315 pounds suggested)
  2. Weighted dips (30 percent of your body weight)

Rest 5 minutes, and then:

  1. Front squat (225/165, suggested)
  2. Barbell row (225/165, suggested)
