HOW TO MEASURE

All measurements above are taken from the garment laid flat. To compare against a shirt you already own and love, lay it flat on a hard surface and measure with a tape.

Body Length

From the highest point of the shoulder seam straight down to the bottom hem.

Chest Width

One inch below the armhole, measured straight across from edge to edge. Garment laid flat, not doubled.

Sleeve Length

From the center back of the collar, across the shoulder seam, all the way down to the sleeve cuff.

Shoulder Width

From the outer edge of one shoulder seam straight across to the outer edge of the other.

Inseam

From the crotch seam straight down the inside of the leg to the bottom of the hem.

Waist

Across the top of the waistband, edge to edge. Double the number for full waist circumference.

Tolerance is the acceptable variance per garment. A "+/- 1" tolerance means the actual measurement can be up to one inch over or under the listed size.

Earthquake Bar A Must Have

I've had shoulder issues because I did a lot of stupid ego lifting when I was younger. This bar has tons of upside. It is great for recovery. Due to the instability it is a great training tool to automatically enforce tempo and correct the path of the bar on the lift. And since it is a stability tool, it requires you to go much lighter that a normal lift which makes benching a lone a little safer.

The earthquake bar

The earthquake bar truly earns its name . It is deceptively light and sturdy . The grip is fatter than a normal Olympic bar . It is excellent for working shoulders and chest . The bar shakes under relatively light loads and forces you to compensate. I have two screws in my shoulder and limited mobility and diminished strength . The bar is perfect for equalizing the load because you can’t compensate the strength of one arm for the weakness in another. And because you can’t both shoulders get fair and attention. Please note I am a novice layman but to me it works .

Very happy with Earthquake Bar

Received my Earthquake Bar order very quickly and I live in Canada! Less than a week from the day I ordered it! Great job! The bar itself I use twice a week on my upper body day training sessions. Tough bar to use however the instability on using it will great increase the strength of my rotor cuff muscles...it hammers them using the bar for high reps! I bigger bench is on the way! Thanks Westside and Louie of course!

Earthquake bar

Few years now I had a year to wait in county jail to go up state so people who know what I'm talking about nothing to do in county jails so other then push ups chin ups sits ups handstand push ups and BW squats I filled a few bags up with water and started to curls and trim ex with the bag at first I'd rock alot and it was heavy then as time want doing them when I was finally able to touch some real barbells and dumbbells some how I was even stronger with my curls and EX. So when I got out read about this bar now I understand why I got stronger thanks Westside barbell for putting this 411 out there
