Few things are better than a massage after a workout or a hard day at work. If you can't always have someone to massage you, it makes sense to do it yourself. Foam rollers are popular for this but they're limited compared to what the MOBO System can do. It's a modular self-massage tool dubbed the Swiss Army Knife of mobility, which means you don't have to carry the dozen or so tools like foam rollers, massage balls, and what-not. It provides multiple and interchangeable tools in one portable device.
A study at McMaster University in Ontario, Canada, found that having a massage after a workout improves recovery by decreasing inflammation caused by exercise and increasing the production of mitochondria (the stuff in your cells that's crucial for energy generation) in the muscles.
Also an article at Men's Heath suggest that the secret to greater strength and size is flexibility.
