Female offspring (G₂) body mass (a), percent fat mass (b), and percent lean mass (c) at 3 weeks of age. Individuals were exposed to the following maternal experimental conditions: no maternal exercise (standard mouse cage), post-weaning maternal exercise (access to a running wheel up until the time of mating), and post-weaning and gestational maternal exercise (access to a running wheel until two days prior to giving birth). General Linear Models [Univariate GLM ANOVA (SPSS, Chicago, IL)] revealed marginal effects of maternal exercise condition on body mass (F_{2, 42} = 3.089, p = 0.056) and percent lean mass (F_{2, 42} = 3.356, p = 0.044), but not on percent fat mass (F_{2, 42} = 2.289, p = 0.114). Means ± standard errors of untransformed data are presented for each trait
