Ricci's training regimen is as intense as you would imagine for a professional fighter—she is no stranger to lifting heavy weights. "Strength training may enhance your quality of life and improve your ability to do everyday activities," says the Mayo Clinic. "Strength training can also protect your joints from injury."

Appropriately for someone with the nickname Baby Shark, Ricci loves deep-sea diving. Scuba diving is a great way to get aerobic exercise while having a magical experience. "Learning my way through the deep water 🦈," she captioned an Instagram video.

Ricci frequently utilizes resistance bands as part of her training routine. "Resistance bands recruit the 'stabilizer' muscles – this muscle group is significant because it supports our larger muscles and joints when we move, and helps reduce the risk of injury," personal trainer Jen Skym tells Live Science. "So they are a safe and low-impact option for older people, and are often used for rehabilitation."

Ricci loves quinoa bowls with healthy protein and vegetables. "Though technically a seed, Quinoa is classified as a whole grain and is a good source of plant protein and fiber," says Harvard Health. "One cup cooked provides about 8 grams of protein and 5 grams of fiber."

Ricci enjoys energy drinks and coffee for a boost. "[Coffee] acts on your brain to improve memory, mood, reaction times and mental function," says the Cleveland Clinic. "One study even says caffeine can improve endurance and performance during exercise."
