The Science

Wrist and forearm position during the biceps curl on biceps muscle soreness
The biceps curl is a hallmark of strength training programs. For the curl, the wrist can be positioned with the palms facing up (supinated biceps

Squat depth and adaptations to training
The squat exercise has been a hallmark of strength training programs for decades. When performed correctly, the squat can significantly improve lower-body muscle strength. But

Impact of COVID-19 on eccentric muscle strength in soccer players
The COVID-19 global pandemic has impacted life in many ways, including the ability to participate in sports and exercise. In a recent study, sports scientists

Eccentric training with one arm makes the other arm stronger
An eccentric muscle contraction occurs when a muscle creates force as it is lengthened. In the squat exercise, for example, the quadriceps and gluteus muscles

Low-load eccentric exercise increases muscle strength
A concentric muscle contraction occurs when a muscle creates forces as it shortens (e.g., upward lifting phase of the biceps curl exercise). An eccentric muscle

80 weeks of resistance training in older adults
One limitation of exercise research is that study durations are usually not very long, often lasting only a few weeks to a couple of months.
