I'm looking to build muscle; do I have to lift heavy?
If you're struggling to get to grips with the barbell, then have no fear: deadlifting your own weight in cold, hard iron may not be necessary!! Research by Lehman College in New York suggests lifting lighter weights for more reps can be just as effective as doing fewer heavier reps.
Study author Dr Brad Schoenfeld says: "Training a muscle at, or near, fatigue causes an adaptive response that favours growth and strength. Heavier loads appear to maximise the strength response while lower-load training leads to greater improvements in muscular endurance."
So, does that mean lifting heavy is a thing of the past? Not really - it's all about what you're hoping to achieve. 'For instance those who simply want to look and feel good, it doesn't matter particularly how heavy your weights are, as long as you challenge the muscles to a high degree.' Very uplifting...
