This fitted CW-X Ventilator Web long-sleeve top doesn't just outline your curves in hot pink piping and create the illusion of an hourglass shape, but kinesiology taping technology also creates a support system to help improve your posture and give you more controlled movement in your shoulders and arms. And vented side panels keep you cool—even when you're chasing your personal record.

Hidden power-mesh panels smooth your stomach, back and sides without making you feel like you're squished into a sausage casing. Even better, no itchy tag rubbing between your shoulder blades means you can stay focused on your form while you're lifting weights.

Ruched sides on this fitted electric tunic (available in plus sizes) can be cinched up to give you free range of movement during yoga, but they can also be pulled down to cover your hips and bum on your walk home from class. If you want to stretch outside in the park instead of a studio, UPF 50-plus fabric keeps skin protected from ultraviolet rays.

A higher neckline with the look of a layered cami, thicker straps and a built-in shelf bra offer additional coverage and support for bigger busts. And the Empire-waist cut will graze over your middle while you work off any postholiday bulge. Bonus: Two built-in back pockets give you a place to stash your cell phone and locker keys—meaning you'll never forget them in the cup holder on the treadmill again.

Attention pear shapes: Gathering at the top of this Lija tank boosts your bust, balances proportions and helps you look less bottom-heavy.

Asymmetrical color blocking on this lightweight Adidas long-sleeve tee makes you look leaner during an early spring run when the weather is still chilly and you're getting into bathing suit shape. The best part: Darker shades at the top mean you can wear any color sports bra underneath without it showing through.
