We get a lot of questions regarding gym attire and it’s a topic I’ve been meaning to cover. Not only does it hit close to home for me, but improving the physical shape of your body is probably the best thing you can do to look better in your clothing (not to mention out of your clothing).

When I’m in the gym I’m often dumbfounded by the things guys will wear to workout. From frumpy (and often dirty) cut-off t shirts, to weird graphic hoodies, to jeans and sandals.

Keep in mind, as always, when you look good, you feel good. And when you feel good, you get a better workout. Believe it or not, it makes a difference, and it’s amplified in an atmosphere like a public gym where you’re constantly looking at yourself in the mirror (and perhaps comparing yourself with others).

Self confidence improves (in athletics, business, or whatever else really) when you look the part. And self confidence without a doubt improves performance. I can say this from experience, even from my days on the basketball court.  Ball players in their fresh Js testify here.

As I’ve said time and time again, the starting point of good style is practicality and functionality. This is never more true than at the gym. Maybe it’s because I’m a former athlete and a proper workout regimen has been bashed into me, but I was never one for “fashion” at the gym. Appropriate attire is the name of the game.

So to address this subject, I thought who better to demonstrate proper gym attire than my longtime friend Luc Bernatchez – one of the most knowledgeable and committed trainers/bodybuilders you will ever meet.

Here, Luc gave us a quick rundown of what he wears to the gym (and why).

1. The Half Zip Pull Over + Knee Length Shorts

“When I’m working out my lower body, shorts are necessary. I want to watch the form of my legs, keep them cool and allow for a full range of motion. I typically wear a long sleeve top to keep the rest of my body warm between sets.

Look for apparel that breathes. There are plenty of Dri Fit and Clima Cool fabrics readily available now, from Nike to Adidas to Under Armor. The technology in these fabrics actually does make a differene. You want to stay warm, but not overheat… And you don’t want to be sweating all over my machines either! haha.”

Bonus Tip: Most of the clothing in this post would be considered tight, but for body building it’s supposed to be. You want to be able to watch your muscle do the work to ensure proper form and to have an extra element of psychological push through those last sets.

Bonus Tip II: As with any other outfit, keep the palette mostly muted and subtle with one affluent color at most.

Bonus Tip III: Look for a classic athletic sneaker, like an Air Max, that is even parts cool and functional. Keep the socks low, especially if you’re working on those calves.

Bonus Tip IV: An ipod is a great idea as it discourages others to engage in forced conversation when you’re trying to get shit done. You should have a playlist that gets you in the zone, long enough to last your entire workout. Don’t waste time flipping tracks.

Bonus Tip V: Some dri-fit shirts are made with built-in pockets for your ipod in convenient places that don’t get in the way of your workout. Genius.

Bonus Tip VI: Instead of having the wire from your headphones in the way of your routine run it up under your shirt.
