Among elite male handball players, lifting heavier weights during training leads to faster throws compared to lifting moderate weights, suggesting that increasing maximum strength has a stronger...

Among elite male handball players, lifting weights with heavy or moderate loads increases upper-body power compared to not doing extra training, but this improvement is due solely to larger muscles,...

In elite male handball players, training with moderate weights for 10 weeks increases upper-body muscle size by about 2.9%, but does not lead to greater improvements in strength or throwing speed...

Among 20-year-old elite male handball players, performing heavy resistance training twice a week for 10 weeks leads to greater improvements in upper-body strength, power, and throwing speed compared...

In untrained men, adding isolated arm exercises to a workout routine may cause the muscles that straighten the elbow to grow more in certain areas than the muscles that bend the elbow, while the...

For men who are new to weight training, doing exercises that work multiple muscle groups at once—like squats and push-ups—can build strength and reduce body fat slightly, without needing exercises...

Doing isolated arm exercises like bicep curls or tricep extensions alongside a full resistance training program does not lead to more fat loss around the upper arms than resistance training alone in...

For beginners who are new to weight training, doing only compound exercises like squats and bench presses leads to the same strength gains in six key lifts as doing those exercises plus isolated...

In untrained young men, adding isolated arm exercises to a full-body weight training program for 8 weeks led to a slightly larger increase in arm size compared to full-body training alone, but there...

For trained male powerlifters, lifting lighter weights for more repetitions leads to the same increase in chest size as lifting heavier weights for fewer repetitions, as long as the total work and...

Among trained male powerlifters, lifting lighter weights for more repetitions and lifting heavier weights for fewer repetitions lead to similar gains in relative strength, and these gains come from...

In trained male powerlifters, performing bench presses with lighter weights and more repetitions leads to larger increases in arm size than using heavier weights with fewer repetitions.

For trained male powerlifters, performing bench press exercises with lighter weights and more repetitions leads to a greater increase in movement speed at 80% of their maximum lift compared to using...

For experienced male powerlifters, lifting lighter weights for more repetitions over 12 weeks can lead to the same increase in maximum strength as lifting heavier weights for fewer repetitions, as...

Participants in the study were given protein and calorie supplements, which may have helped them build more muscle than they would have on their normal diet.

In men new to weightlifting, a specific workout routine using dumbbells for rows and biceps curls, done twice a week for eight weeks with maximum effort per set, leads to high participation rates and...

Measuring muscle thickness at three different points along the upper arm gives a more accurate picture of muscle growth than measuring just one spot or using arm circumference.

When untrained men perform dumbbell rows with one arm and biceps curls with the other, the arm that performs a specific exercise gets stronger at that exercise, but not necessarily at the other...

In men who have not previously trained, performing 8 weeks of biceps curls results in more muscle growth in the upper arm than performing dumbbell rows, suggesting that exercises targeting a single...

When total workload and effort level are kept the same, drop sets, tempo-controlled lifting, and cluster sets result in similar muscle growth and strength improvements as traditional multiple-set...

Among advanced weight training techniques, velocity-based training and eccentric overload lead to the greatest gains in maximum strength in people who train recreationally, primarily because they...

In adults aged 18–45 who train regularly but are not elite athletes, different ways of organizing resistance training sets do not lead to meaningful differences in muscle growth. The amount of work...

In adults aged 18–45 who train recreationally, advanced resistance training methods lead to a small but measurable increase in maximum strength compared to standard multiple-set routines, likely due...

For people who regularly lift weights, training with a little bit of effort left in the tank (1–2 reps before failure) produces the same total amount of work and number of repetitions over eight...
