ACSM analysis of 30,000 participants: regular resistance training matters more than program complexity

The American College of Sports Medicine (ACSM) has published an analysis of 30,000 participants in total, which concludes that resistance training is effective in many different forms, Linternaute.com reports linternaute.comLinternaute.comlinternaute.comOpen source ↗. The analysis stresses the importance of loading all the main muscle groups at least twice a week linternaute.comLinternaute.comlinternaute.comOpen source ↗. According to the study's author, consistency of practice matters far more than the search for a "perfect or particularly complex" program linternaute.comLinternaute.comlinternaute.comOpen source ↗.

The material also notes that this is not a call for a single fixed scheme. The analysis presents resistance training as a broad category that can take many shapes, and it does not tie results to one specialized method linternaute.comLinternaute.comlinternaute.comOpen source ↗.

Frequency, volume and effort

High-intensity resistance training at least twice a week is described as a sound approach linternaute.comLinternaute.comlinternaute.comOpen source ↗. For muscle growth, the ACSM mentions a higher weekly volume, for example ten sets per muscle group linternaute.comLinternaute.comlinternaute.comOpen source ↗. Even so, quantity and effectiveness are said to matter more than complexity linternaute.comLinternaute.comlinternaute.comOpen source ↗.

Training is not limited to lifting dumbbells in a gym. Home exercises that use body weight, for example with resistance bands, have positive effects according to the study linternaute.comLinternaute.comlinternaute.comOpen source ↗.

Many people assume that good training goes to complete exhaustion. A separate study of trained adults found similar gains in strength and muscle hypertrophy after five weeks, whether the training was done very close to failure or not. The ACSM synthesis confirms this linternaute.comLinternaute.comlinternaute.comOpen source ↗.

A simple weekly scheme and protein intake

On paper, the rule for gaining muscle mass is described as simple: two to three sessions per week. They include exercises for the legs (squats, lunges), back (band rows), chest (push-ups), shoulders, arms and abdominals (planks) linternaute.comLinternaute.comlinternaute.comOpen source ↗. What matters is to load each large muscle group regularly through the week and to increase the load gradually linternaute.comLinternaute.comlinternaute.comOpen source ↗.

Exercise alone is not enough. The International Society of Sports Nutrition recommends a daily protein intake of about 1.4 to 2.0 grams per kilogram of body weight for most adults who want to build or maintain muscle mass linternaute.comLinternaute.comlinternaute.comOpen source ↗.
