can you put regular weight plates in the bag to increase weight?

We recommend using the included weights that come with this product to assure that it works as desired.

If using on grass will it kill the grass?

No- the SpeedSac will not kill grass.

i live in AZ grass is scarce out here. will this die on pavement/parking lot ? lol

It’s good on grass, astroturf etc. I can’t vouch for pavement, concrete, gravel etc.

My 14 year old son said it easy just Velcro it around ur waist.
