4×4 around the Dragon’s Den

Get Max Heart Rate

What Is My Maximum Heart Rate?
As you exercise, your heart rate will elevate. Your maximum heart rate is:

220 minus your age

Training with a heart rate above this level can be dangerous. It is advised to work at a level that suits your fitness levels and heart health.

The Norwegian 4×4 workout outlines a target heart rate of 85%-95% of your max heart rate. If you don’t have a fitness tracker that measures heart rate, aim to push yourself to a level of exertion that is 8 or 9 out of 10, where talking feels challenging.

4×4 Workout
To complete the Norwegian 4×4 workout:

Warm-up

Complete a low-intensity warm-up for 10 minutes. This could be a light jog and dynamic stretches.

Intervals

4 minutes each interval of a cardio exercise of choice, at 85-95% of your maximum heart rate. This could be running, swimming, rowing, cycling or high-intensity bodyweight exercises. If you’re running, this could be your 5k or 10k pace.

Active recovery

3 minutes rest of low-intensity activity like brisk walking or jogging, taking your heart rate down to 60-70% of your max heart rate.

Repeat

For a total of 4 high-intensity intervals and rests.

Cool down

Bring down your heart rate slowly, then stretch.

Crab Sack

Two Qs at The Fort
Fishstix Q:
Lap around the park stopping at each swing for warm – ups (SSHs, IWs, WMs, HBWs, MNCs). Stopped at the hill near the monument for a motified Dora. Both partners performed the standard exercises (Merkins, Squats, LBCs). At the completion of half the total reps (50, 100, 150), we moved to the top of the hill. First round was a run, second- wheelbarrow, third – bear crawl. With a few minutes left, we moseyed back to the theater for a few minutes of wall sits, bear crawl merkins.

Cohiba Q:
Ran to each swing and performed the number of reps with the number on the top of the swings by doing burpees, seal jacks, and Lunges at each swing. We started with 9 reps and went down to 1 rep. After the last swing we ran to the front of the amphitheater and did 3 Rounds of 10 reps each of Merkins and jump squats then during Round 1 after the exercises we bear crawl to a concrete pad and back, during Round 2 we did the same exercises with a crab walk to the concrete pad and back, and during Round 3 we did the same exercises with a Run to the concrete pad with a Nur on the way back. Then we just ran 1 loop around the park to COT
Mary: American Hammers until the time was up.

We work hard and had alot of laughs. While we were crab walking. I shared a story about a friend who was crabbing. If you haven’t tried it, it should be on your bucket list My friend caught a crab in his net and attempted to dislodge it from the net into a bucket. Unfortunately, when it flew off the net, it grabbed on to the first thing it hit, his nut sack. One in a million shot.
