Blok Training System

I'm only 15 and I love these jumps because there light enough to were I can carry them around to make my own jumps. But I only use them as little warm up jumps before going to the big course. Like everyone else is saying it's not a good idea to stack them high like the picture, I tried doing that (not quite that high though) and when a big gust of wind came it knocked it all down and during that process, spooked my horse.

Our riding program has been on going for 25+ years and for 15 of these years we have had these blocks(which stay in the outdoor arena ALL year)! Great for pole work and introducing riders to jumps. Also good for warming up an advanced horse before a big course.

They are not meant to be a show/ a huge jump, they are just for practice. They are light, and easy to carry! I really like them! Would buy the red and blue brand though!

Stacking huge piles of these blocks does look like a risky business. However, they are fabulous for raised cavaletti or small X-rails, either individually or combined into gymnastics. They are very inviting to the young horses. The older horses play over them on loose rein as part of the warm up for bigger fences and courses. The blocks are also wonderful on their side to fill in a jump under the rails. Cheaper than buying gates or boxes - and easier to move. The blocks have survived outside in my arena (even through the winter)for at least five years, now. (Note: We get heavy wind and rain storms but stay above freezing in the winter. Any plastic is going to get brittle in freezing weather.)

This is a really great system to use for cavaletti or small jumps. I use it often at the 24" level and I think it can be safely stacked with one laying flat and another on top. I wouldn't stack it the way it is in the ad. If you're looking for a bigger jump I wouldn't reccomend this.

I agree that these are quite unstable. I use them for 9" cross rails and would never recommend stacking them as shown. They are made of material that reminds me of milk containers, but a bit thicker. Each one is quite light, making it easy to set up, but very unstable. If you have a quiet horse and looking to do some very light caveletti work, I highly recommend these. Otherwise, invest in something more substantial.

These blocks are great to build jumps in smaller arenas. They are easy to pull in and drag out. I leave mine out in all weather and they have held up wonderfully. The only thing that I dont like about them is when they do finally break, the pieces are sharp and could be very harmful if your horse were to step on them. Also you cannot stack them like they advertise. They will tumble down and scare any horse around.
