Editing Strength training (section)

===Weekly frequency===

In general, more weekly training sessions lead to higher increases in physical strength. However, when training volume was equalized, training frequency had no influence on muscular strength. In addition, greater frequency had no significant effect on single-joint exercises. There may be a fatigue recovery effect in which spreading the same amount of training over multiple days boosts gains, but this has to be confirmed by future studies.<ref>{{cite journal |last1=Grgic |first1=Jozo |last2=Schoenfeld |first2=Brad J. |last3=Davies |first3=Timothy B. |last4=Lazinica |first4=Bruno |last5=Krieger |first5=James W. |last6=Pedisic |first6=Zeljko |title=Effect of Resistance Training Frequency on Gains in Muscular Strength: A Systematic Review and Meta-Analysis |journal=Sports Medicine |date=22 February 2018 |volume=48 |issue=5 |pages=1207–1220 |doi=10.1007/s40279-018-0872-x |pmid=29470825 |s2cid=3447605 |url=https://vuir.vu.edu.au/37695/1/Effect_of_Resistance_TrainingFrequency_on_Gains_in_Muscular_Strength_A_SystematicReview.pdf }}</ref>

For muscle growth, a training frequency of two sessions per week had greater effects than once per week. Whether training a muscle group three times per week is superior to a twice-per-week protocol remains to be determined.<ref>{{cite journal |last1=Schoenfeld |first1=Brad J. |last2=Ogborn |first2=Dan |last3=Krieger |first3=James W. |title=Effects of Resistance Training Frequency on Measures of Muscle Hypertrophy: A Systematic Review and Meta-Analysis |journal=Sports Medicine |date=21 April 2016 |volume=46 |issue=11 |pages=1689–1697 |doi=10.1007/s40279-016-0543-8 |pmid=27102172 |s2cid=207494003 }}</ref>
