Purge old workout gear.
Socks wear thin, sports bras lose support, waistbands stretch out, and the UPF in sun-protective clothing decreases with each wash. Toss exercise clothing that is worn out and donate what you don't wear. Tennis shoes last for about 300 to 400 miles of activity. Get fitted for a new pair, and donate those past their prime to a program such as Soles4Souls.
