PMID 27543047WHAT IT FOUND
Isometric handgrip strength was only modestly related to maximal bench press strength and overestimated it by 4.7 kg on average.
Do not use handgrip alone to judge breast cancer survivors' bench press strength.
Key findings
01All isometric handgrip strength metrics were significantly correlated with maximal bench press strength, but the correlations were modest, with correlation coefficients from 0.29 to 0.39.
02Mean isometric strength of both hands was the strongest correlate of maximal bench press strength, at 23.5±5.8 kg with correlation coefficient 0.399.
03Isometric handgrip strength overestimated maximal bench press strength by 4.7 kg on average, with reported 95% limits from -8.2 to 17.6 kg, and the overestimation was consistent across the strength range.

What it does not show
This was a secondary analysis of a randomized trial, not the trial's primary intervention outcome. The participants were breast cancer survivors who were eligible for an exercise trial, so they may not represent all breast cancer survivors.
Declared interests
No conflict-of-interest declaration is included in the supplied text. The publication type lists NIH extramural research support.
The easy way to misread this
Do not read the significant correlations as evidence that handgrip measures the same thing as bench press. The correlations were modest, and handgrip overestimated bench press by 4.7 kg on average.
