It looks a little crooked but our yard is just bumpy.
We have been getting some great leg workouts with this Endurance Pro Speed and Agility Ladder. There are so many different drills you can do with this piece of equipment. I love that the rungs are adjustable. They just slide up or down easily so you can change it up a bit. If you have bigger feet like a few of our boys it's easier for them to be farther apart when they are doing some of their jumps. I just have them do extra to make up for it. :)
The ladder also comes with a bag so you can easily roll it up and take it with you. We've just been using it in our backyard. I'm having the boys use it as part of their Phys Ed. I just can't sit on the sidelines so we all take turns calling out what drills we're doing as we go. We love anything that keeps us from getting bored.
You can find this Endurance Pro Speed and Agility Ladder on Amazon.
