fitness resistance band

Today sunday ! sunday sport yes! i have discovered a few montsh ago the perfect accessory to realize your fitness exercices easily !

the firness resistance band! for the girl my advice to begin it's red or black band. You can buy online or fitness shop. 
i use it cause i have some back trouble so it's a good way to practice. You can use for : arms, back, shoulders, chest, legs doing squat with it lateral raises etc. 
You can find online on youtube a lot of routine practice videos. 

the point i like : compact you can bring with you on luggage, bags etc :)
