Buy these and shape your play area around them. I have linoleum laminated floors and they are pretty shiny, doesn't really interfere with tracking.

I over estimated most of the prices, but these are things I figured I would need in a home gym if I ever build one. If you take out a few, you can make it fit your budget.

Are there any suggestions for mats when doing bodyline drills?

I notice /u/Antranik often uses a yoga mat, and when I do them (especially side plank) on my carpet, or hardwood floor, my feet and hands can end up hurting quite a bit (yes, I'm bony :))

I focus a lot on proper form (since I'm a beginner and want to avoid bad habits), so I'm also considering it might be due to bad form, or just plain weakness since I'm significantly worse at side plank than the rest of the exercises (20s compared to 40-50s).

If it's not, I'm considering buying a foam mat, anyone who can recommend it?
