Home Gyms

So I've been planning out some before work gym routines.. but recently our gym's new (4 month) dollamur mats seems were coming off (factory defect with the glue).  So they made and installed a new floor. Luckily for me, the seller was able to keep the defect and with very little work able to repair the mats.

So, I bought an end roll (with no defects) for home.  6x36!   I'll cut it in two and have a great mat space for home. And can wake up and do some conditioning right at home.

That said,  what kinds of conditioning equipment are a must haves for a home gym? (namely to for BJJ)

So far:

exercise ball for core,stability training
skipping rope
medicine ball

Hopefully I can find a kettle bell or two.
