Gym goers who
are keen to develop an impressive physique may be tempted to grab
the heaviest dumbbells and start lifting.

But they may
be putting themselves through unnecessary suffering, a new study
has revealed.

Researchers
from McMaster University found that lifting lighter weights for
longer is just as effective at bulking up the body.

The secret
is to pump iron until you reach muscle fatigue.

‘Rather than
grunting and straining to lift heavy weights, you can grab something
much lighter but you have to lift it until you can’t lift it
anymore,’ said Professor Stuart Phillips.

‘We’re
convinced that growing muscle means stimulating your muscle to make
new muscle proteins, a process in the body that over time accumulates
into bigger muscles.’

The study used
light weights that represented a percentage of what the subjects
could lift.

The heavier
weights were set to 90 per cent of a person’s best lift and
the light weights at a mere 30 per cent of what people could lift.
