I will keep this short and sweet.
I tried a one armed long cycle with 12kg for 6 minutes switching hands on the minute with an emphasis on technique.
I did 6 reps per minute for the first 4 minutes and 14 reps per minute on the last two minutes.
It did not feel sufficient for the day.
And since I don't want to push the weight I need to do more reps but I'm impatient and wanted to do 1000 reps in minimum time.
So, on a whim I did 12 kg one armed swings for fun, one switch. It pans out to 500/500 and took approximately 28 minutes.
I can't or should try to lift heavy for about 4 weeks but I can get a good workout with 12 kg. Granted I've been laying around doing nothing for two weeks straight and had lost a quart of blood or more. The low iron count from the blood loss affected my energy level and walking around and interacting became taxing.
As of yesterday I felt normal in that it wasn't.
Its about how you feel and I felt good about this set of 1000 with 12 kg. So the work done was 12000kg in one set.
