An excellent 5 minute video of Erica Kern showing off her excellent leg and glute development while performing squats.
Erica started competing in 1992, turned pro in 1995 by winning the North Americans and competed in the IFBB pro leagues until retiring in 1998.
Are thongs practical to squat in? Possibly not, but when you look like Ericca it’s all good.
If you enjoyed watching Ericca squatting while wearing a thong, check this post which shows fitness icon Monica Brant also squatting wearing a thong.
