After you've put in the hard work, it's easy to head home without going through a proper post-workout regimen, but stretching is essential.
After all of the reps you did during your workout, your muscles are left shortened. Proper post-workout stretching helps reset your body. While stretching might not help with post-workout soreness, it can help with mobility and increase your range of motion—a payoff that could help ensure you're reaching the full-range of motion on each and every rep. Post-workout, make sure to hold static stretches for about 30 seconds each, and aim for a total of 15 to 20 minutes of cool-down.
