A new training routine and what the wardrobe is missing
Short answer: Two sets of activewear and four extra pairs of socks and underwear are enough to start. Buy the rest once you know what you actually train.
Start with the smallest possible
Most people buy too much at the start and discover after two months that they train something other than they expected. Two sets washed between sessions cover three sessions a week.
What is really missing
What gets forgotten is extra underwear and socks. Training three times a week means three extra sets on top of the daily need. See bamboo underwear for men.
What bamboo fabric can and cannot do
For light and moderate training, bamboo viscose is comfortable and smells less than synthetic. For hard endurance training, synthetic is lighter and dries faster. See bamboo activewear for women and bamboo sports bra.
Frequently asked questions
Should activewear be washed after every session
Yes. Sweat and bacteria settle into the fibres quickly.
Can you train in an ordinary t-shirt
For light training yes. For sweaty sessions it gets heavy.
What matters most to get right
Socks and underwear. They decide whether chafing becomes a problem.
