Blood flow restriction training uses inflatable cuffs and light weights to try to build muscle without heavy loads. Recent studies show it works about as well as standard rehab or heavy lifting, but not better. It may be most useful when heavier exercise is not an option.
Trapezius hypertrophy, or an overdeveloped upper trapezius muscle, is increasingly common due to modern lifestyle habits. Research shows that Botox injections can reduce muscle thickness by about 13% at peak effect, with high patient satisfaction, though results are temporary and repeat treatments are needed.
Your quadriceps are four separate muscles that require thoughtful training to grow. Research points to full range of motion, a mix of compound and isolation exercises, adequate weekly volume, and progressive overload as the key drivers of quad hypertrophy.
Two recent studies examined whether training muscles in a stretched position produces more growth. For the hamstrings, the answer was a clear yes. For the biceps, the two positions produced nearly identical results. The difference may come down to how much each muscle's working length actually changes.
A 2024 study found that taking a full week off from training in the middle of a 9-week program didn't help or hurt muscle growth in trained young adults. However, continuous training produced better strength gains than including a deload week.
A 2025 study found that dumbbell and cable lateral raises produce identical lateral deltoid growth in trained lifters. Meanwhile, research on elbow angle suggests keeping your arm straighter may increase muscle activation. Here is what the evidence means for your shoulder training.
New research breaks down the science of bodybuilding nutrition, from protein targets and post-workout recovery to what 33 top coaches actually recommend. Here's where coaching wisdom and lab evidence agree, and where they don't.
Your lats are the biggest muscle in your body, yet they have been surprisingly understudied. New research reveals how they grow at the fiber level, whether extra protein helps, and why your grip width on the pulldown barely matters.
Falls are the leading cause of injury in older adults, but research shows they're largely preventable. Exercise programs targeting balance and strength, home safety modifications, and medication reviews can significantly reduce fall risk when combined in a tailored approach.
"Runner's knee" actually refers to several distinct conditions, mainly patellofemoral pain and iliotibial band syndrome. Research shows that targeted exercise, running technique changes, and proper diagnosis are key to recovery, and that recreational running does not appear to damage healthy knees.
