(Ivanhoe Newswire) -- We all know exercise is good for us, but finding the time to do it can be a challenge. If only we could pop a pill instead...

Thanks to new research out of the Salk Institute, hope is on the horizon. In studies conducted in mice, investigators there not only discovered a substance that increased exercise endurance among mice that were exercised daily, but also one that lead to greater endurance even without the daily exertion.

“It’s tricking the muscle into ‘believing’ it’s been exercised daily,” study author Ronald Evans was quoted as saying. “It’s basically the couch potato experiment, and it proves you can have a pharmacologic equivalent to exercise.”

Both of the substances are currently available. GW1516, which proved beneficial in increasing exercise endurance in mice that exercised, is an experimental drug being tested for the treatment of metabolic disease. Overall, mice who received the drug along with four weeks of exercise training increased their running time by 68 percent when compared to similar mice who trained but received a placebo instead of the active drug. Running distance went up by 70 percent.
