Just keep doing them. The soreness will go away. Good for you for making a start.
Here’s an article that explains a bit of what’s going on.

April 21, 2006 — Lactic acid may go from being disrespected to desired by athletes, based on new research.
When skeletal muscles work (such as during exercise), they release lactic acid. If lactic acid builds up during intense exercise, it can make muscles sore.
But lactic acid has more to offer than that, report George Brooks, PhD, and colleagues. Brooks is a professor of integrative biology at the University of California, Berkeley. He specializes in exercise physiology and metabolism.
Brooks and colleagues report their latest findings on lactic acid in the American Journal of Physiology — Endocrinology and Metabolism. Their article, currently in press for the journal’s print edition, recently appeared in the journal’s online edition.
Lactic Acid as Fuel
Brooks’ team studied lactic acid (also known as lactate) in cells taken from rats’ skeletal muscles. They found that under certain conditions, those cells’ powerhouses, called mitochondria, can use lactic acid as fuel.
Those findings could translate to intense interval training in people, Brooks says, in a news release. Interval training involves brief bursts of extreme effort, followed by gentler recovery periods.
“The world’s best athletes stay competitive by interval training,” Brooks says, in the news release. “The intense exercise generates big lactate loads, and the body adapts by building up mitochondria to clear lactic acid quickly. If you use it up, it doesn’t accumulate.”
Of course, most people aren’t elite athletes. The findings shouldn’t be taken as a license to go overboard in your workouts. Brooks’ study focuses on the science of how cells use lactic acid. It doesn’t provide any exercise tips to make the best use of lactic acid.
