For all you Oly lifters out there:
I'm looking at putting a home gym together, but the budget is very tight so I need to choose equipment very carefully. I've recently started performing O-lifts regularly and don't want for this to stop due to lack of bumper plates. Unfortunately these cost a lot and would break the budget very quickly, so I was wondering how many bumper plates does one need to drop the bar safely on to a platform?
For example, if I had a single large diameter 20 or 25 kg bumper plate each side and the other plates were smaller diameter 10,5,2.5 etc kg regular iron plates which would not hit the ground, is this OK?
The only concern I would have with doing this is that by adding the smaller plates the inertia of these plates would continue as the larger bumpers hit the ground, flexing the ends of the bar excessively as the small plates continued to fall without resistance and concentrating the full force of the drop where the single bumper plates hit the ground. Alternatively, by using the normal all-bumper plate setup the impact is absorbed over a wider area, distributing the stress on the bar a lot more.
As I have just started the O-lifts it will be a while before I will need more than two of the large bumper plates each side as I would rather practise technique first and get it right. Then I can add more bumpers when I can afford them and have progressed to using a higher load.
Thoughts/suggestions? What do you use at your home gyms for O-lifts?
