 concrete but now it's a good environment to play in because you can train with soccer shoes with cleats you'll just slip and fall. It's like a real soccer field where professionals play. I think I'll train here more because it's a more suitable area than the other areas I usually train in. I can do a lot of drills with cones here. I can also practice my juggling and stuff. Yes I would recommend this because in the wintertime you really can train outside and if you have your turf inside your house it would help a lot.
