Peak 7's base area is composed of two large lodges, the Crystal Peak Lodge and the Grand Lodge on Peak 7, and is connected to town by one of two midway stations on the BreckConnect Gondola. The base area also has a restaurant, Sevens, opened in February 2009.
Massage can help tight muscles release and loosen up a stiff and sore lower back. All you need is a a foam roller. Place the foam roller under your lower back and place your feet flat on the floor. Using your feet for leverage, roll up and down on the foam roller over the muscles that are tight and tender.
If you feel the tightness on the back, more in your middle traps and between your shoulder blades, you won't need to do yoga exercises to reach there with the tennis ball. Find a wall and lean against it with the tennis ball between and roll up and down. Again, when you find a tough spot, stay there for a while.
