Happy June! This month, it’s all about the clamshell, the best beachy exercise for the booty and inner thighs. To get clammy, lie down on one side. Bend legs to a 45 degree angle at knees and hips. With heels stacked, open top knee and close like a clamshell, keeping heels together. Save, print, or pin the image below and clamshell your way right into beach season!
