Shorter, Heavier Lifting Sessions Can Still Yield Major Strength Gains, Study Finds

Busy schedule? New research suggests you can still achieve important strength gains by focusing on shorter, more intense weightlifting sessions using heavier weights.

Instead of long workouts with numerous repetitions using lighter weights, prioritize fewer sets with heavier loads. While longer gym sessions can be enjoyable when time permits, a recent study offers valuable insights for those with limited time.

Here’s a breakdown of the study’s findings and why lifting heavier weights for shorter durations can still lead to considerable progress.

Study findings: Quality Over Quantity

The study, published in sportrxiv (a pre-print server), analyzed numerous existing studies to determine how training volume per session impacts muscle growth and strength gains.

Researchers found that while multiple sets can contribute to muscle building, performing just one or two intense, focused sets with heavy weights can result in significant strength improvements, particularly for individuals who train consistently several times a week.

Unsurprisingly, increased sets per session correlated with increased muscle size and strength. Though, muscle growth benefits plateaued after approximately 11 sets per session. For strength building, the advantages leveled off after two direct sets of a single movement per session.

The key takeaway is that more repetitions aren’t always superior. Adding extra sets might simply waste time and energy. Instead, prioritize lifting heavier weights.

The lower amount of reps you do, the higher weight you should use. Stressing your muscles more can build more lean muscle.

The Advantage of Fewer Sets with Higher Load

Lifting heavier weights for shorter periods can effectively stress muscles, leading to greater results, according to experts.

“The lower amount of reps you do, the higher weight you should use,” he says. “Stressing your muscles more can build more lean muscle.”

Determining the Right Weight for Your Lifting Sessions

Aim for a range of eight to 12 repetitions in most cases. “Pick a weight where you think you can do that over three to five sets with good form,” he says. “If you start to go over 12 reps consistently, add more weight.”

If completing eight repetitions proves challenging, reduce the weight. “Try a weight and see how many reps you can do,” he says. “That a good way to start.”

Optimal Weightlifting Frequency

Incorporating weightlifting and strength training is beneficial for various aspects of health, from metabolism to bone density. The study indicated that lifting approximately two times per week is helpful, aligning with current exercise guidelines recommending at least 150 minutes of moderate-intensity exercise per week, along with two days of strength training.

Ideally, aim to lift weights more frequently, rotating muscle groups daily.
