After once having a lot of weightlifting equipment, I can tell you I am happy to keep the minimum- 1 rack, 1 eleiko bar, 1 non-needle bar, a set of eleiko weights, and a few odd small items for abs and such. That is enough to drag around from place to place when you move as it is IMO. I don't want more equipment anymore. The last thing I would ever want to own again is a set of jerk blocks.
Yes, I meant the big wood ones, but simple squat racks work fine for jerks out of the rack, so I wouldn't want anything else.
Bringing the weight down efficiently takes a lot of practice, but also has some value in learning IMO. Still, when I get to 85%+ in rack jerks, I just dump it, strip it, and power clean it back to the rack for the next rep.
