I've found that, for me, the best way to lower triglycerides was a mix of a regular cardio workout and improving my diet. But when I was diagnosed with Type II Diabetes, the exercise portion seemed to be the biggest key. I dropped my number down to close to what a non-diabetic's triglycerides should be. I don't think the lowering of the number would have been as effective if I just did one of those things, though.

Obviously that's just one person's experience, but lowering that number can definitely be done. The biggest thing is just mental discipline to execute whatever plan you have and keep it consistent. Good luck!
