<sec> <title>BACKGROUND</title> Sedentary behavior among breast cancer survivors is associated with increased risk of poor physical function and worse quality life. While moderate to vigorous activity can improve outcomes for survivors, many are unable engage in that intensity activity. Decreasing sitting time may be a more feasible behavioral target potentially mitigate the impact its treatments. </sec> <title>OBJECTIVE</title> The purpose this study was investigate feasibility preliminary an intervention reduce on changes life from baseline 3-month follow-up. <title>METHODS</title> Female self-reported difficulties received one-on-one, in-person personalized health coaching sessions aimed at reducing time. At follow-up, participants wore activPAL (thigh-worn accelerometer; PAL Technologies) 3 months completed tests (4-Meter Walk Test, Timed Up Go, 30-Second Chair Stand) Patient-Reported Outcomes Measurement Information System (PROMIS) outcomes. Changes sedentary were assessed by linear mixed models. <title>RESULTS</title> On average, (n=20) aged 64.5 (SD 9.4) years; had BMI 30.4 4.5) kg/m&lt;sup&gt;2&lt;/sup&gt;; identified as Black or African American (n=3, 15%), Hispanic Latina (n=4, 20%), non-Hispanic White (n=14, 55%). Average since diagnosis 5.8 2.2) years receiving chemotherapy (n=8, 40%), radiotherapy (n=18, 90%), endocrine therapy (n=17, 85%). led significant reductions time: average daily decreased 645.7 72.4) 532.7 142.1; β=–112.9; &lt;i&gt;P&lt;/i&gt;=.001) minutes long bouts (bout length ≥20 min) 468.3 94.9) 366.9 150.4; β=–101.4; &lt;i&gt;P&lt;/i&gt;=.002) minutes. All improvements: 4-Meter Test performance 4.23 0.95) 3.61 2.53; β=–.63; seconds, Go 10.30 3.32) 8.84 1.58; β=–1.46; &lt;i&gt;P&lt;/i&gt;=.003) Stand 9.75 2.81) 13.20 completions β=3.45; &lt;i&gt;P&lt;/i&gt;&amp;lt;.001).
