Question: Can I use these in an outdoor setting?
Document: These mats are great, I actually use a stack of them on top of my 3/8" mats for a barbell I use for bentover rows and deadlifts, so far the floor hasn't cracked so I think these mats are doing a great job!
These gym mats are good for their intended use. They protect your floor while you work out with free weights.
The mats mostly stick together and stay in place. The corner piece seems to get pulled and pushed out of shape so that it does not always fit nicely. We use them as mats for insanity and have only once notice my feet catch on the interlocking pieces. Most of they time they fit together seamlessly. Pretty good for what we use them for  may get more to create a bigger workout zone.
The tiles were just the right amount of thickness and I could connect them easily to fit my floor. Thank you.
These mats are working very well in my gym. They came with plenty of the side pieces (trim), which is what i was afraid that I might not have. A lot of the mats I reviewed stated that there was not enough trim to make the mat area look nice\finished. THese are great...
Looks great when you put them together...but man!!! Slip and slide. :-(I purchased these mats as I'm doing a p90x and Insanity hybrid workout. The mats are ok when I'm walking around with weights, but worse than useless for any cardio activity.Essentially when I do cardio, or anything that puts sideways tension on the mats (i.e, yoga) the mats will split on the connection points. Very frustrating.
easy to put togeather. so far they hold up well. i put mine over a carpet floor to make a workout room. they still hold togeather and work great. covers a large area. cost less then any i bought in the store. they even matched the old ones i already had from a different company. good buy.
We bought these for our home gym and office room. They are flimsy, rip apart from each other easily. Don't grip to any type of floor, so that causes shifting of the area.
Purchase something else.
