The Smartest Way to Do Cardio for Fat Loss and Health

Cardio Mistakes and General Approach00:00

Doing lots of cardio at 160 to 180 beats per minute for 60 minutes at a time for muscularity is a mistake. Cardio that causes a lot of fatigue will limit muscle gains. The trade-off is between leanness and health versus how much muscle you will gain. Getting really aggressive with cardio right at the beginning is a bad idea. Starting with 30 minutes per session, six sessions a week can lead to shin splints, ankle issues, and psychological burnout. How hard to go is a technical question, not an emotional question.

Introduction to Evidence-Based Cardio Recommendations00:30

For 2026 cardio recommendations, lazy answers like "just do more steps" are insufficient. A logical map of what kind of cardio to do and when is needed regardless of goals. Two main things to discuss are the biggest guiding question for cardio and the variables that matter. The biggest question is your goal, which creates very different recommendations.

Five Goal Classes for Cardio Recommendations01:31

Five classes of goals are defined for cardio recommendations. Class one is strength power, including weightlifters, throwers, and powerlifters. Class two is muscularity, focusing on getting as jacked as possible while being pretty lean. Class three is health, optimizing for health outcomes. Class four is leanness, wanting to get as shredded as possible. Class five is endurance, training specifically for endurance sports. Each class will cover modalities of cardio, intensities, durations, and weekly frequency.

Cardio for Strength Power03:00

For strength power athletes like powerlifters and weightlifters, modalities include walking, swimming, and elliptical. Intensity should be kept under 140 beats per minute, which is low intensity without getting crazy out of breath. Duration should be under 30 minutes per session. Frequency can be three to six times per week. The real unlock is getting about 8,000 daily steps, which is already good for strength power athletes. Going beyond this in difficulty and frequency, such as 140 beats per minute for 30 minutes six days a week on the elliptical, will cost potential gains in strength.

Cardio for Muscularity04:31

For muscularity goals, modalities include walking, swimming, and elliptical. Intensity should be under 140 beats per minute to prevent fatigue that interferes with training sessions. Duration should be under 60 minutes at a time, which is more permissive than strength power because muscle size retains itself better in the face of cardio than muscle strength or fiber type. Frequency can be three to seven times per week. A shortcut is 8 to 12,000 steps per day, and some tougher cardio is okay, but fatigue from cardio will limit muscle gains. Between 8 to 12,000 steps and up to seven 60-minute sessions at relatively low heart rate, the choice depends on desired leanness and health versus muscle gains.

Cardio for Health06:00

Any modality is fine for health, including sport and dance. Intensity can range from 120 to 200 beats per minute, including a little bit of each. Duration can be 15 to 60 minutes at a time, three to six or more days per week. The bottom end adaptive window for health effects starts at three sessions a week of 15 minutes at something above 150 beats per minute that makes you breathe heavy. A baseline of 10,000 steps a day is recommended, but walking alone is not enough to optimize health. Three sessions of 15 minutes each at 150 beats per minute plus is a good start. The top end is six sessions a week of 60 minutes at 150 beats per minute plus. As long as recovery, sleep, and strength are maintained, there are no wrong answers between these parameters.

Cardio for Leanness08:00

For leanness goals where upper body muscle is maintained but leg size is not a priority, all modalities and variations are fine. Intensity can be anywhere between 120 and 200 beats per minute. Duration ranges from daily steps to one hour of dedicated cardio, potentially hard cardio. Frequency can be daily steps or up to six times a week of hard cardio at 150 beats per minute plus for an hour. This burns serious calories. Six sessions of 60 minutes at 150 beats per minute plus will help get leaner, assuming recovery capacity. Starting slower and increasing is recommended. 10,000 daily steps alone can achieve desired leanness, but adding cardio allows faster results and additional health benefits. A combination of 10 to 12,000 daily steps and three to six sessions of 30 to 60 minutes at 150 beats per minute plus weekly will produce significant fat loss.

Cardio for Endurance10:00

For endurance training, all modalities apply and should be specific to the sport. Intensity ranges from 150 beats per minute up to short bouts of 200 beats per minute. Duration can be 30 minutes for some sessions, 60 minutes for others, and up to 120 minutes or more for long swims, rides, or runs. Frequency should be at least four days a week up to seven days for elite athletes. Serious endurance training can start at three days a week with 30-minute sessions at 150 beats per minute plus. Once above five weekly sessions, waving intensity and duration pays dividends rather than running linearly at one speed every day. Switching modalities often prevents overreaching and injury. Swimming and cycling are good replacements when giving joints a break from running.

Endurance Training Recommendation12:30

For serious endurance training, getting a coach is highly recommended. The speaker's knowledge of endurance training is limited compared to hypertrophy knowledge. Alex and Michelle Harrison are recommended as endurance coaches.

Summary of Recommendations by Goal13:00

For strength and power, 8,000 daily steps with not much else is recommended, especially during serious training or competing phases. For maximum muscle gain, 10,000-ish daily steps is excellent, though three weekly sessions of 15 to 30 minutes at 150 beats per minute is fine. For health, the more cardio the better as long as recovery, strength, muscle, and sleep are maintained. Three weekly sessions of 15 minutes at 150 beats per minute is the bottom end, with four to six weekly sessions of 30 to 45 minutes at 150 to 200 beats per minute providing optimal health benefits. For leanness, as long as recovery and strength are maintained with 10,000 minimum steps, more cardio produces better results. Steps from cardio count toward the daily total. For endurance, professional coaching or an app is recommended.

Cardio Do's15:00

Find what's fun to ensure sustainability. Find what's sustainable for your joints and switch modalities if one causes pain. Find what you can be consistent with, considering location and available equipment. Track your steps to know exactly how much cardio you're doing and to ensure calorie deficit calculations are accurate.

Cardio Don'ts16:30

Don't start with aggressive cardio programs that lead to injury and burnout. Start with lower frequency like three times a week, 15 minutes per session, and intensity that barely gets you out of breath, then increase gradually. Don't assume one modality is categorically superior and reject variation. Don't freak out about cardio killing gains. Excessive cardio first slows gains, then stops them, then causes slight recession. Don't continue with a painful modality when injured. Try alternatives like swimming which is joint-friendly. Don't be inflexible about taking breaks during vacations. Don't punish yourself with cardio. How hard to go is a technical question based on body needs, not emotional needs or punishment.
