Packing your workout gear in an already-jam-packed carry-on bag is an easy excuse to not work out while on a business trip. Well, it was. In a long-overdue partnership, Westin has teamed up with New Balance to provide footwear, apparel, and fitness programs to hotel guests beginning with 10 hotels, including Tokyo, Maui, Berlin, and the Boston Waterfront, in early 2011. Guests can borrow running shoes with disposable insoles for each use during their stay, as well as a variety of apparel. New Balance celebrity trainer Holly Perkins designed multiple workouts for guests in-room or in the gym. There are no more excuses for not hitting the gym next time you hit the road and stay at a Westin.

COST: Free for hotel guests.
