WASHINGTON — Wal-Mart said Friday it is hiring 100 new people to help run its midwest headquarters and will launch a new fitness program at its retail stores in the region.

Walmart also announced plans to buy an undisclosed number of equipment manufacturers for the midwest.

The retailer said it expects to begin operating its first outdoor shopping centers and expand the company’s existing physical grocery stores.

Wal-Mart also plans to open a new gym in the city of Omaha this summer.

The gym will be open to the public and will be equipped with a treadmill and other equipment that can help people lose weight.

The company also announced that it has signed a new 10-year partnership with U.S. Postal Service that will make its mail delivery service more efficient, more efficient and more efficient in its mission to deliver mail more efficiently and more reliably.

WalMart is the largest private employer in Omaha and has more than 2,500 stores and distribution centers in the metro area.
