Two of the authors of the review also made a study    5    (publish) in 2014    6    showed a mere 5 to 10 minutes a day of running reduced the risk of heart disease and early deaths from all    7    (cause).

The best exercise is one that you enjoy and will do. But otherwise … it’s probably running. To avoid knee pain, you can run on soft surfaces, do exercises to    8    (strength) your leg muscles, avoid hills and get good running shoes. Running is cheap, easy and it’s always    9    (energy).

“A project which allows the people of Japan     4     (participate) in creating the medals is really good, and helps raise the environmental awareness of our citizens,” said Tokyo 2020 sports director Koji

Murofushi. “    5     the resources of our earth are limited, we need to recycle more and avoid waste. This program is setting     6     example.”

Collection boxes have been placed in local offices and telecom stores and they will remain there until the metal required     7     (collect).
