How can I raise my HDL levels?

I have been seriously trying for about 5 years to raise my HDL level without success. Currently, my levels are: HDL 34, LDL 58, total Cholesterol 122 and Triglycerides 149. Presently, I am daily taking Lipitor (20mg), Niacin (800mg) and fish oils (10,000mg). I started taking prescription niacin about 4 months ago.

For the past year I been off of my exercise program. However, during this period, I have been very active physically doing house projects 4-5 hours per day. The previous 4 years my exercise program consisted of jogging and using a treadmill 5-7 days a week @ 1 1/2 hrs daily. Even during those 4 years, my highest HDL reading was only 42.

Bottom line, considering I get back to my exercise program, what else can I do to raise my HDL level? Thank you in advance
