Lift Some Weights

Lifting weights is obviously great for your strength, but it can
also boost your brain power, improve your immune system, and even
reverse signs of cellular ageing. Michael enlists Jenny, a
self-confessed weight lifting novice, to try strength training at
home using milk bottles and a sturdy rucksack. He speaks to Dr.
Teresa Liu-Ambrose at University of British Columbia, Canada who
has recently found that strength training can lead to better
memory. She reveals how activating your muscles can release
special chemicals called myokines which astonishingly, can travel
around the body and cross your blood-brain-barrier where they can
have beneficial effects on your brain.
