According to the National Center for Health Research, music doesn't just relieve boredom. It can also improve the quality of your workout by putting you in a better mood. What's more is that some sounds can engage certain networks in your brain that allow your muscle groups to sync with the music.

It's worth investing in a pair of earphones that can keep you in the zone as you workout. Jabra's Elite Active 65T ranks as the best earphones for running and the gym, thanks to their wireless fit, sound isolation, and decent battery life. And while you're at it, give the Best Body Ever playlist a listen here!

To "dress for success" doesn't just apply to work. At the gym, high quality fabrics work as hard as you do to accelerate your performance. Your oversized cotton shirt from high school probably won't withstand rigorous training.

And when it comes to doing your best, comfort is the key. Choose leggings, tops, and shirts in soft fabrics that allow maximum breathability. They should also be durable enough to see you through your squat session or an hour-long Vinyasa practice. However, if you're the type to workout outdoors, it may be best to layer up so temperature drops don't get in the way. Woman Within's hooded jackets will help you survive those chilly morning jogs, while still providing you enough room for movement. Plus, they're easy to throw on and off at any point if it gets too warm. Pair it with LNDR'S trusty sports bras, which feature chic designs and antibacterial fibers to wick away the cold sweat.

Just because you aren't loading up on your weights doesn't mean you aren't hard at work. So grab that two- or three-pounder if that's what you're comfortable with (for now), because a 2012 study by researchers from McMaster University confirms that using light weights can be just as effective.
