It is common knowledge that the most efficient and effective way to build muscle is through resistance training. Typically, those who want to build size jump straight into an intensive gym routine that includes some form of a split. However, results vary from person to person based on genetics. It is not typical that those who do the same workout routine get the same results.
Researchers have looked into the variation in muscle and strength size within resistance training workout between genders.
The Study
342 women and 243 men were assigned a progressive resistance-training program for biceps. Participants trained just the weaker arm, thereby allowing the stronger arm to act as a control. Each person’s one rep max and strength was tested before and after the 12-week program.
The Results
Among participants, the researchers found a massive difference in bicep sizes. These measurable differences ranged from -2 to +59% growth in bicep, which equated to a growth of between -0.4 to +13.6 cm2. Participants’ one-repetition maximum strength increase varied between 0 to +10.2 kg.
As you might expect, men saw the best gains in size and strength. However, men had only a slight advantage in relative size gains compared with women, whereas women outpaced men considerably in relative gains in strength.
This study shows that there is a significant difference in how we benefit from resistance training which is something we should consider while exercising. Don’t compare yourself to others and enjoy what you have.
