The purpose of the proposed study is to measure surgical recovery, including the length of hospital stay, incidence of perioperative complications, and mortality at 90 days post-surgery, in surgical patients with abdominal cancer. The investigators hypothesize that this prehabilitation program will improve recovery and reduce perioperative complications via the proposed prehabilitation intervention.
The investigators propose that steps to augment and optimize the effectiveness of prehabilitation interventions for abdominal cancer patients may be found in the field of sport science. The investigators have identified two primary strategies to improve and optimize prehabilitation in patients with abdominal cancer: exercise and nutritional supplementation. A home-based exercise program incorporating both walking and resistance training will be performed with blood flow restriction training (BFR). BFR is a cutting-edge training modality that works by restricting blood flow out of the veins by using compression devices similar to traditional blood pressure cuffs (1). This training modality is frequently used by injured athletes for enhanced recovery (2). Muscle hypertrophy and increased muscle strength are more robust and achievable with BFR, even if exercises are performed at low to moderate intensities (2). Additionally, the implementation of a sports nutrition supplement cocktail, which will be provided simultaneously with the 4-week BFR exercise intervention, was developed to augment the effects of resistance exercise by increasing overall anabolism (3) and to remedy the catabolic state that cancer patients often experience (4). The nutrition supplement cocktail will include whey protein, creatine monohydrate, and L-citrulline.

| Prehabilitation Program | Combination Product | This is a 4 week prehabilitation program which uses both exercise and nutrition. Exercise will be prescribed at least 6 days a week. Three days a week , for 45 mins, participants will be asked to perform body, leg and arm exercises against light resistance while wearing pneumatic blood flow restriction arm and leg bands. minutes. On the alternate days participants will walk approximately 15 minutes while wearing the leg bands that restrict blood flow. Additionally, a nutrition supplement cocktail will be provided and should be taken every day within 1 hour after completing each exercise session. The 4 Week Nutrition (Sports Drink) Supplement Cocktail: will include whey protein (25 g/day), creatine monohydrate (8 g/day), and L-citrulline (5 g/day). The supplement mixture will be provided in daily packages by the investigators (nutrition supplements are not regulated by the FDA) |

100 subjects between the ages of 18 and 90, who have GI cancer and will undergo surgery will be recruited for this study. 100 is an arbitrary number of participants. Due to this study design not being previously use before power analysis calculations were unable to made for key variables. All subjects will participate in the study design.

| Physical Fitness- SPPB | Short Physical Performance Battery Assessing Lower Extremity Function | Baseline and 4 weeks |

| Questionnaires- Health Status | Health research questionnaire; self reported medical and health history of participant. | Baseline |
| Questionnaires- IPAQ | International Physical Activity Questionnaire; self reported time, frequency and duration of physical activity within the last 7 days. | Baseline and 8 weeks |
| Questionnaires- SF36 | SF-36 Quality of Life. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. | Baseline, 4 weeks, and 8 weeks |
| Questionnaires- MMSE | Mini Mental State Examination (MMSE) 30-point questionnaire that is used extensively in clinical and research settings to measure cognitive impairment. Score is reported as 0-30 . 24-30 indicates no cognitive impairment, 18-23 indicates mild cognitive impairment, and 0-17 indicates severe cognitive impairment. | Baseline |
| Questionnaires- FESI | Falls Efficacy Scale-International; items are summed to calculate a range of total score from minimum 16 to maximum 64. The higher the score the greater the fear of falling. | Baseline, 4 weeks, and 8 weeks |
| Questionnaires- Nutrition | Dietary Food and Supplement Intake; self reported nutrition intake from 2 weekdays and one weekend. | Baseline |
| Questionnaires- Charlson Comorbidity | Charlson Comorbidity Index predicts the one-year mortality for a patient who may have a range of comorbid conditions, such as heart disease, AIDS, or cancer (a total of 22 conditions). Each condition is assigned a score of 1, 2, 3, or 6, depending on the risk of dying associated with each one. Scores are summed to provide a total score to predict mortality. | Baseline |
| Questionnaires- BSCI | Brief Screen for Cognitive Impairment (BSCI); Scores are weighted and summed to arrive at final score. Delayed recall and medication help each get a weight of 2.0, and errand help gets a weight of 1.0. If client does not take any medications, the weighted scores of the other two items perform similarly to the three-item version. Higher scores indicate greater frailty/cognitive impairment. | Baseline |
| Questionnaires- Edmonton Frailty | Edmonton Frailty Assessment; consists of nine domains and eleven items, each scoring 0 points (frailty absent or normal health), 1 point (minor errors or mild/moderate impairment), or 2 points (important errors or severely impaired). Higher scores indicate greater frailty. | Baseline |

| Questionnaires- Clock Test | Clock Test; evaluates three items: "correctly drawn clock shape," "all numbers in the correct position," and "hands of the clock set to the correct time." A score of 1 was assigned for each of these items. Higher scores indicate greater frailty/cognitive impairment. | Baseline |
