AI synopsis

What people are saying

The discussions reflect a consensus that isolated exercises are unnecessary once muscles are sufficiently stimulated through compound movements, using words like 'no need' and 'made NO DIFFERENCE' to underscore their agreement. Participants cite the study to support practical training advice, with some referencing related studies or experiences, indicating a moderate but shared recognition of the findings' relevance.

AgreementStrong agreement

The majority of posts strongly agree with the study's conclusion that adding single-joint exercises offers no extra benefit, emphasizing points like 'NO DIFFERENCE' and 'no need for isolation.'

InterestModerate interest

Posts indicate moderate interest, largely focusing on confirming the study's findings and their practical implications, without overly emotional or passionate language.

EngagementModerate engagement

Comments show some thoughtfulness, referencing the study and sharing opinions, but lack deep discussion or debate, mostly agreeing or slightly elaborating.

ImpactModerate impact

The discourse suggests the study reinforces existing beliefs about training efficiency, which could influence training approaches, but the overall impact appears moderate.

Abstract in brief

  • The study investigated whether adding singlejoint exercises to a multijoint resistance training program would lead to greater muscle growth and strength gains in untrained men.
  • Results showed that both training styles increased muscle size and strength significantly, but there was no significant difference between doing only multijoint exercises and combining them with singlejoint exercises.
  • Overall, including singlejoint exercises did not provide extra benefits for muscle growth or strength development in untrained young men.

@BradSchoenfeld There's no need for isolation exercises for muscles already worked to failure by compound exercises - e.g. direct biceps exercises after chinups. Here's a study showing that adding this isolation work after compounds made NO DIFFERENCE. https://t.co/FRjuwc44OB

However, there is no need isolation for muscles worked to failure by compound exercises - e.g. Biceps after chinups or triceps after overhead press. Here's a study showing that adding this isolation work after compounds made NO DIFFERENCE. https://t.co/FRjuwclGdb

@jerryteixeira @B_Holmer I was thinking of that study (that you actually brought to my attention) that compared single joint exercises after multi-joint vs. multi-joint alone https://t.co/FRjuwclGdb

@fancypirate8 If you properly stimulated those muscles with a compound exercise first, there's no additional benefit from doing them. https://t.co/FRjuwclGdb
