The study examined the impact of weight machines training on selected strength factors among different BMI of male college students. Sixty-six males aged 19 to 23 years participated in this investigation. The subjects were distributed into four groups; Underweight Group1 (UWG1, n = 14), Normal Weight Group2 (NWG2, n = 25), OverWeight Group3 (OWG3, n = 19) and Obese Group4 (OG4, n = 8). The strength measurements were seated chest press (CP), seated leg press (LP), and seated abdomen (Abdo) workouts, performed before and after training. One Repetition Maximum (1RM) was used to decide the maximum strength of all subjects. The training involved several weight machines such as leg press, abdomen, chest press, pull down, row, and leg extension. The data were analyzed using a One-Way Analysis of Variance (ANOVA) and t-test (Paired). The significance level was 0.05. The OG4 revealed meaningfully greater mean different value than the NWG2 (17.46 ± 6.79, 10.92 ± 5.66 kg, respectively, P = 0.02) in Abdo when post-tests were subtracted from pre-tests (mean differences). When paired t-test was used, the UWG1 revealed significant increases in BM, LP, Abdo, and CP by 2, 42, 38, and 35%, respectively, the NWG2 by 2% (BM), 31% (LP and Abdo), and 25% (CP), the OWG3 by 21% (LP), 30% (Abdo) and 20% (CP) and the OG4 by 33% (LP), 36% (Abdo) and 15% (CP). In conclusion, the 4 categories of body mass index enhanced their strength elements after 8 weeks of weight machine training.
