The purpose of this study is to determine whether a program to optimize patient physical fitness and nutrition ("prehabilitation") prior to and after plastic surgery involving the abdomen improves surgical outcomes. The investigators hope to determine how a multimodal peri-operative prehabilitation program can be most effective in engaging and motivating patients to physically and mentally get ready for an abdominally-based plastic surgery operation. The overall goal is to determine if this program will improve post-operative recovery after abdominally-based plastic surgery. The importance of this new knowledge is better understanding of ways that plastic surgeons can improve outcomes, engagement, and experience of patients undergoing abdominally-based plastic surgery operations. This would translate to increased healthcare value and better long-term outcomes.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control | No Intervention | The control arm will receive no additional prehabilitation material prior to material. Rather, they will receive standard preoperative care in which they will be given standard advice on nutrition and fitness. REDcap surveys will be administered. | |
| Prehab Intervention Arm | Experimental | The intervention arm will receive access to the prehab program (abdominal workout videos) and surveys via RedCAP.The program will start no less than 14 days before the date of surgery. |

| Prehabilitation Program | Behavioral | Nutrition component: Participants will receive information on how to follow a healthy diet (Mediterranean-style diet) with emphasis on whole foods, plants, lean protein, olive oil; restriction of red meats, processed meats, processed foods, added sugar) Exercise component: Participants will receive an activity tracker to use during the study period (3+ weeks before surgery, and 30 days after surgery). Participants will be assigned strength exercises to work on core strength and proximal muscle strength (biceps/triceps, quads, hamstrings, calves).The exercises will mainly be focused on strengthening the abdominal wall. Exercises will be tailored to patients' individual capabilities. They will also be assigned cardio exercises - either low-intensity steady state cardio vs High Intensity Interval training. Level of cardio exercise will be tailored based on patient's Duke Activity score and baseline activity. |
