6 Workouts To Try Now + What To Wear (& Not Wear) To Each

Having launched her career under trainer-to-the-stars Tracy Anderson, and a regular go-to for fitness tips amongst the likes of ELLE, Condé Nast Traveler, Well + Good and The New York Times (among others), it’s no wonder Katherine Greiner has quickly become one of the most sought-after personal trainers amongst Manhattan’s elite. And as if that wasn’t a stacked resumé already, we love that Katherine devotes her free time to educating youth on the importance of proper fitness and nutrition as well as advocating for health education reform.

We sat down with the founder of KGBody to get the scoop on 6 workouts to try now, along with her do’s (and don’ts) of what to wear to each – including her own top picks. Hint: DON’T wear baggy clothing to yoga…unless you want to flash your lady bits to the entire class.

1. Yoga

Clothing DO’s: On the bottom, wear form-fitting pieces such as leggings or snug shorts. For tops, a tank with a built-in bra is a great choice.

Clothing’s DON’TS: Don’t wear baggy clothes! Your yoga instructor needs to see your body, especially your knees and the front of your hips. Loose fitting tops will not only end up falling into your face when doing inverted poses such as Downward Dog and Handstand, but in the process expose your top half (hence where a tank with built-in bra comes in handy). I’ll leave it to your imagination what else might get flashed while wearing baggy shorts.

KG’s picks: The Splits59 Ashby Ribbed Tank ($45.00) & Loren Seamless Bra ($39.00), or Alala’s Snap Back Tank ($95.00) with built-in shelf bra. For high-waist leggings ($98.00) in fun, funky prints, try K-Deer.

2. Dance cardio

Clothing DO’s: Do let your personality shine through and use this as an outlet to express yourself. Leggings, crop tops and mesh cut-outs encouraged! I personally prefer to wear something form-fitting on the bottom and loose on the top, OR vice versa – this gives the outfit a sense of movement without looking (or feeling) overly bulky.

Clothing DON’TS: Don’t wear super snug booty shorts! Between all of that jumping, turning and leaping, I have just one word for you: WEDGIE.

KG’s picks: I love Michi’s cut-out Psyloque Legging ($130.00) and Antigravity Bra ($85.00), and Phat Buddha’s slouchy Mysterioso Tank ($55.00). Brazilian label Candida Maria is another great pick for fun, printed leggings ($76.00 – $82.00).

3. Boot Camp Style (e.g. CrossFit or Barry’s Bootcamp)

Clothing DO’s: You definitely want a fully supportive sports bra for these high-impact, versatile workouts. Feel free to wear a loose-fitting tank or tee, and I recommend a capri length legging to protect your knees from getting scuffed when doing floor exercises.

Clothing DON’TS: Don’t underestimate the high intensity of a Boot Camp workout and arrive unprepared! Especially if you’re busty, a low support, bralette-style sports bra simply won’t cut it.

KG’s picks: Reebok’s “Do Your Own Thing” Muscle Tee ($32.00) and Athleta’s Quest Metro Slouch Capri ($79.00). Check out Shock Absorber for great high-impact sports bras ($59.00 – $79.00)!

4. Spin

Clothing DO’S: Mid-thigh bike shorts are key! You want something long enough that will prevent chafing on the bike seat. Sitting on a bike in underwear + shorts (or leggings) can cause additional down-there chafing (not to mention uncomfortable bunching), so I highly recommend looking for bottoms with built-in, absorbent lining. Also, you’re going to sweat (a lot) in spin, so be sure to look for moisture-wicking fabrications in both bottoms & tops.

Clothing DON’TS: Absolutely do not wear long, baggy pants or joggers that can catch on the bike – not only will they be torn, but they can take you off the bike with them!

KG’s picks: Splits59’s Sabrina Performance Tank ($68.00) and Koral Binary Bicycle Shorts ($85.00). Try Dear Kate for shorts, capris & leggings with built-in underwear lining ($66.00 – $158.00).

5. Barre

Clothing DO’S: I love a good pair of grip socks to prevent sliding, and you’re OK with a lower-impact sports bra or tank with built-in shelf bra here. Just like with yoga, stick with form-fitting pieces such as footless tights & leggings so the instructor can see your body and correct where necessary. Stirrup leggings are also great as they’ll not only eliminate the need for socks, but will create a long, slimming leg line.

Clothing DON’TS: Unless you have ballet shoes, don’t wear footed tights – you’re bound to go sliding!

KG’s picks: I love StickyBe socks for their grip and positive mantras. Try Alala’s Cross-Front Bra ($35.00), and Strut This makes great barre-to-brunch leggings ($68.00 – $78.00) that you can dress up (or down) post-class. For a great stirrup legging, try Splits59’s Tendu Grip.

6. The Great Outdoors: Hiking & Cross-Training

Clothing DO’S: When working out outdoors, especially in cold weather, the proper attire is critical. Make sure to wear proper hiking boots when embarking on long excursions, and don’t forget long underwear and a cozy hoodie.

Clothing DON’TS: Don’t be unprepared! Do your homework and research the terrain of where you’re going before embarking on your workout. Dress appropriately and don’t forget proper footwear is CRITICAL for outdoor workouts.

KG’s picks: Patagonia for long underwear (the Capilene Midweight ($59.00) and Thermal ($89.00) Bottoms are great), Ahnu for hiking boots ($140.00 – $185.00) and check out good hYOUman for fun athleisure-style tops & sweatshirts.
