Martial Arts for Fitness and Weight Loss in Riverside: An Honest Guide
November 3, 2026
Training at Flow Academy Riverside can be a strong way to get the regular exercise that weight loss depends on, but no class can promise a number on the scale. The CDC says getting to and staying at a healthy weight takes both regular physical activity and healthy eating patterns. Here is how martial arts fits into that, honestly.
What the Guidelines Say
The CDC’s physical activity guidelines say adults need 150 minutes of moderate-intensity activity a week, or 75 minutes of vigorous activity, plus at least 2 days of muscle-strengthening activity. The CDC also says some physical activity is better than none, and that you can spread it out through the week in smaller chunks.
On weight specifically, the CDC says most weight loss comes from eating fewer calories, that you may need more than the recommended minutes of activity to keep your weight steady, and that regular physical activity is the only way to keep lost weight off. Training helps most when it’s paired with how you eat.
How Many Calories Does a Class Burn?
We don’t publish a calorie number, because there isn’t an honest single one. It depends on your size, how hard you work, how much of the class is drilling versus live rounds, and how long you rest between them. A fitness tracker can give you a rough estimate for your own body; treat it as a guide, not a fact.
Jiu-Jitsu, Boxing, Muay Thai and MMA for Fitness
Brazilian Jiu-Jitsu
Grappling works your whole body at once: legs, hips, grip, core and lungs. Drilling is steady work, and live rounds are short bursts of hard effort. There are no punches or kicks, and you can take a breather whenever you need one.
Boxing
Punching combinations, footwork and defense make for intense cardio and strong shoulders and core, with gloves on.
Muay Thai
Thai boxing adds kicks, knees and elbows to punches, usually trained in hard rounds on pads.
MMA
Mixed martial arts blends striking and grappling, so classes move between both kinds of work.
The best martial art for fitness is the one you’ll keep showing up for. Flow Academy Riverside teaches jiu-jitsu; Muay Thai and adult MMA are taught at Flow Academy Indio.

Start Safely
You don’t need to get in shape before your first class; training is how the fitness comes. Talk to your doctor before starting a new exercise program, especially if you have a health condition. Tell your coach about old injuries, bring water, and go at your own pace. We coach, we don’t give medical or diet advice.
