Things You'll Need:
- Curl bar
-
Step 1
Put an appropriate amount of weight on the curl bar. A good estimate for doing twenty-ones is to use the same amount of weight you use for a set of 10 seated curls.
-
Step 2
Stand over the curl bar, grip it underhanded and lift it up to your chin. Your forearms should be vertical and your fists pointed to the ceiling.
-
Step 3
Lower the bar to 90 degrees, then lift it back to the position of step 2. This is the first part of twenty-ones and is essentially half of a normal standing curl. Repeat this motion 7 times.
-
Step 4
Lower the bar so that your arms are relaxed. The bar should be against your thighs and your arms pointed toward the ground.
-
Step 5
Raise the bar to 90 degrees, then lower it back to the position of step 4. This is the second part of twenty-ones and is essentially the other half of a normal standing curl. Repeat this motion 7 times.
-
Step 6
Finish off the twenty-ones by doing 7 reps of a full standing curl.
