Get the ache off your back
The back often gets short shrift when it comes to strength and conditioning because people tend to focus on muscles more prone to easy definition. But neglecting this body part can lead to stiffness and pain.
To help restore backs to their proper shape, we asked three trainers for their favourite back exercises. Repetitions and set numbers are given as a suggestion.

Exercise can help keep vision sharp
Vigorous exercise may help prevent age-related macular degeneration and cataracts, both of which can affect vision. Two studies looked at data from almost eight years of follow-up from the National Runners' Health Study.
In one, 110 men and 42 women received a clinical diagnosis of age-related macular degeneration. The more the runners ran, the less risk they had for developing age-related macular degeneration.
Running an average of 2-4 kilometres a day reduced the risk by 19 per cent and running more than 4 kilometres per day reduced the risk by 42-54 per cent, compared with those who ran less than 2 kilometres a day.
Running an extra kilometre per day was associated with a 10 per cent decrease in relative risk. Another study which appeared in a recent issue of Investigative Ophthalmology & Visual Science examined the effects of running on developing cataracts.
Among the same group of runners, 733 men and 179 women reported having cataracts during the follow-up. Those who ran 64 kilometres or more per week had a 35 per cent lower cataract risk than those who ran less than 16 kilometres per week.
And those with better cardiovascular fitness were also at less risk than men who were less fit. Although it is not fully known why a link exists between fitness and preventing these conditions, study author Paul T. Williams, a staff scientist with the Department of Energy's Lawrence Berkeley National Laboratory, believes exercise could provide similar protective benefits for the eyes as it does for the heart.
