Gym Hoodie Fit Guide: How a Training Hoodie Should Fit
Chest, length and sleeve measurements for a gym hoodie that moves with you, with a size table and a two-minute measuring method.
By Synergywear / / 1 min read

A good training hoodie keeps you warm through the first sets, then gets out of the way. Fit decides both. Here is exactly what to measure and what the numbers should be.
What a good fit looks like
Three points matter more than the size letter: chest ease, body length and sleeve length. Get these right and the hoodie will not ride up on a press or bunch at the elbows on a pull.
Measure flat: armpit to armpit for chest, high shoulder point to hem for length.
Synergy hoodie size chart
All measurements are of the garment laid flat, in centimetres. Double the chest figure for the full circumference.
Size | Chest (flat) | Body length | Sleeve | Fits chest |
|---|---|---|---|---|
S | 54 | 68 | 62 | 86 to 94 |
M | 57 | 70 | 63 | 94 to 102 |
L | 60 | 72 | 64 | 102 to 110 |
XL | 63 | 74 | 65 | 110 to 118 |
XXL | 66 | 76 | 66 | 118 to 126 |
How to measure in two minutes
Take a hoodie that already fits you well and lay it flat on a table.
Measure straight across the chest, 2 cm below the armpits.
Measure from the highest point of the shoulder down to the hem.
Compare both numbers with the chart and pick the closest size.
Fit by training style
Lifting: size up if you are between sizes. Extra room across the back helps on overhead work.
Running and conditioning: stay true to size or go down for less fabric movement.
Layering: size up so a tee or rash guard sits underneath without pulling.
Rule of thumb: if you can raise both arms straight up and the hem stays below your belt, the length is right.

Frequently asked questions
Should a gym hoodie be oversized?
Only if you want the look. For lifting, 10 to 15 cm of chest ease is enough to move freely without fabric catching on the bar. Oversized cuts add 20 cm or more.
Do Synergy hoodies shrink?
Our heavyweight cotton blend is pre-shrunk. Wash cold and dry flat and the measurements in the table stay the same within about 1 cm.
What if my size is not listed?
Choose Other size on the product page and type your measurements. We confirm the fit with you before cutting.
