Post-Workout Ice Baths May Weaken Muscles

Taking a post-workout ice bath — a technique promoted for relieving muscle soreness — may actually reduce gains in muscle mass and strength, a small new study suggests. The other half cooled down actively, by riding exercise bikes after each workout. The researchers found that, at the end of the study, muscle strength and mass increased more in the men who cooled down on exercise bikes than in those who took ice baths.
