I recently bought new sweatpants, and I have a great recommendation for anyone looking for great sweatpants.
Amazon has these sweatpants available for only around $30.
I can personally attest that they are very comfortable and are exactly what you need for sitting around in the house.
I always come back to one of my main beliefs about lifetime training and exercising: You have to have good workout clothes.
Same goes for recovery. You need warm, comfortable clothese, so you can lie on the couch and allow your muscles to recover. There are way too many hardo 110% effort type trainers out there who don’t even understand recovery. If you are not doing recovery, you are not training the right way, won’t get results, and certainly won’t get the strength and power gains you’re looking for.
