Feeling tight and stiff in your back, are you restricted in how far you can turn your back, do you experience discomfort when you lean forward or back and do you feel tender areas in your back?
I would recommend for this type of problem stretching, always warming up before exercise, cooling down after, lower back exercises and strength work.
Sports Massage Therapy can be highly effective to treating this problem, this is because I can feel the back and palpate to see where the tender areas are. It is very much possible to treat the back, ridding it off adhesions, trigger points and scar tissue. With a massage of this type clients can feel an instant relief, the solid restricted texture of muscle can be released allowing more movement and flexibility.
Having a tight rigid back, will also affect other muscle groups so it is not uncommon to feel a postive change in other muscle groups after treating the back.
