For full flexibility when doing yoga, or for full extension when doing squats at the gym, a pair of running tights is perhaps the most useful athletic garment to have. It is also functional, serving to keep legs warm in winter, and some also offer compression to aid in lymphatic drainage, enabling the legs to become more svelte and toned. They also have the added bonus of being slimming due to clever designs and color blocking techniques. Stars like Kate Hudson, who has designed her own line, show that a pair of running tights is cute and girly and a perfectly good alternative to shorts. Try them the next time we workout, we might just be pleasantly surprised.
