Strong, on plants.
Every gram of muscle you want can be built without meat. It just takes slightly more intention.
The short answer
Vegetarians build muscle and fitness on par with meat eaters in the research, once total protein is matched. The catch is that plant proteins come in smaller doses per plate, so hitting 1.2 to 1.6 grams per kilogram of body weight takes planning where a chicken breast takes none.
Where the protein lives
Eggs and dairy carry vegetarians furthest: Greek yogurt, cottage cheese, milk and eggs are complete, cheap and easy. From plants: lentils, chickpeas, beans, tofu, tempeh and edamame lead; a cup of cooked lentils holds about 18 grams. Nuts and whole grains contribute steadily in the background. A day that includes dairy or eggs at two meals and legumes at one usually lands on target without arithmetic.
The complete-protein worry, retired
Plant proteins vary in their amino acid mix, but eating a normal variety across the day fills every gap; the old rule about combining proteins at the same meal was retired decades ago. Soy, quinoa, and anything with dairy or eggs are complete on their own anyway.
The two nutrients to actually watch
Iron absorbs less well from plants, and low ferritin is the most common reason a vegetarian feels flat in training, especially for women; vitamin C with meals helps, and a blood test settles it. B12 is non-negotiable for vegans and worth checking in vegetarians. Everything else, including creatine for those who train hard, is optional fine-tuning.
Training changes nothing
The strength and cardio guidance on this site applies unchanged: two strength sessions, movement most days, progression when it gets easy. Plants fuel it fine. If you want your plan built vegetarian from the start, say so on the Personal Plan form and the coach builds every meal that way.
Not magic, just convenient
Useful when your plan calls for more protein than your meals reach, especially for older adults protecting muscle. Whey or a plant blend both work; unflavored mixes into anything.
