You can do far more than you probably think, even with no equipment, limited space, or achy joints. The current guidelines recommend 150 minutes of moderate-intensity activity per week plus two days of strength training. That’s the target, but the real answer to your question is bigger: there are hundreds of exercises spanning cardio, strength, flexibility, and low-impact movement, and the best ones for you depend on your starting point and what you enjoy enough to keep doing.
Cardio Exercises by Intensity
Cardio (aerobic exercise) is anything that raises your heart rate and keeps it elevated. Scientists measure exercise intensity using METs, or metabolic equivalents, which compare an activity’s energy demand to sitting still. You don’t need to memorize MET values, but the three tiers they create are useful for planning.
Light intensity (1.6 to 3.0 METs): slow walking, fishing while seated, playing a musical instrument, light cooking or dishwashing. These count as movement and are a legitimate starting point if you’re currently sedentary.
Moderate intensity (3.0 to 6.0 METs): brisk walking at about 4 mph, light cycling (10 to 12 mph), recreational badminton, doubles tennis, vacuuming, mopping, mowing the lawn with a push mower. This is the zone the 150-minute guideline refers to. A simple test: you can talk during moderate activity but not sing.
Vigorous intensity (6.0+ METs): jogging at 6 mph, fast cycling (14 to 16 mph), singles tennis, basketball, soccer, hiking uphill, shoveling heavy loads. Vigorous exercise counts double toward the weekly target, so 75 minutes of jogging substitutes for 150 minutes of brisk walking. You can also mix and match moderate and vigorous sessions throughout the week.
Strength Training Essentials
Strength work builds muscle, protects your joints, and improves how your body handles everyday tasks like carrying groceries or climbing stairs. The simplest way to organize it is around the basic movement patterns your body was built for. Covering all of them ensures you’re training every major muscle group.
- Squat/knee-dominant: bodyweight squats, lunges, Bulgarian split squats, low step-ups. These target your quads, glutes, and hamstrings.
- Hip hinge: Romanian deadlifts, kettlebell swings, single-leg deadlifts, glute bridges. These emphasize your glutes, hamstrings, and lower back.
- Horizontal push: push-ups (or modified push-ups on your knees), bench press. These work your chest, shoulders, and triceps.
- Horizontal pull: inverted rows, bent-over rows, doorframe rows. These hit your back, biceps, and grip.
- Vertical push: overhead press, push press. Shoulders and triceps.
- Vertical pull: pull-ups (any grip width), lat pulldowns. Back, biceps, and shoulders.
- Core: planks, bird dogs, sit-ups, reverse crunches. These stabilize your trunk and protect your spine.
You don’t need to do all of these in every session. Picking one exercise from each pattern, two to three times a week, covers the CDC’s recommendation of at least two days of muscle-strengthening activity targeting all major muscle groups.
No-Equipment Workouts
You can build a complete routine using nothing but your body and a floor. The key is matching exercises to your current fitness level so you can actually do them with decent form.
A solid beginner routine done twice a week might include bodyweight squats, modified push-ups, a doorframe or table row, split squats, glute bridges, planks, penguin crunches, and bird dogs. That covers your legs, chest, back, glutes, and core in eight exercises.
Once that gets easier, progress to standard push-ups, backward lunges, single-leg deadlifts, up-down planks, and sit-ups. At an advanced level you can swap in jump squats, feet-elevated push-ups, single-leg squats, V-ups, single-leg elevated glute bridges, and rotating side planks. Each tier uses the same movement patterns but demands more strength, balance, or power. You can also add triceps dips using a sturdy chair to target the backs of your arms.
Low-Impact Options for Sensitive Joints
Joint pain or stiffness doesn’t mean you should stop moving. In fact, the opposite is true: regular low-impact exercise reduces arthritis pain and improves range of motion over time. The goal is to keep your joints moving without subjecting them to jarring forces.
Walking is the simplest option and one of the most effective. Swimming and water aerobics are particularly joint-friendly because the water supports your body weight while still providing resistance. Cycling, whether outdoors or on a stationary bike, lets you build leg strength with minimal impact. Gentle yoga and tai chi improve flexibility, balance, and body awareness while being easy on your hips, knees, and ankles. All of these qualify as aerobic exercise and can count toward your weekly 150 minutes.
Stretching and Warm-Up
Stretching matters, but when and how you stretch makes a difference. Dynamic stretching, where you move through a range of motion without holding a position (leg swings, arm circles, walking lunges), is the better choice before a workout. It raises body temperature, increases blood flow, and has been shown to improve sprint and muscular performance. Static stretching, where you hold a position for 20 to 30 seconds, can temporarily reduce the contractile force of your muscles, so save it for after your workout when your muscles are warm and it can help with recovery and flexibility.
How to Progress Over Time
Your body adapts to exercise relatively quickly, especially in the first few months. To keep making gains, you need to gradually increase the challenge. This principle, called progressive overload, is straightforward to apply. Each week, try one of these adjustments:
- Add weight: increase the load by roughly 2.5 to 5 percent.
- Add reps: do one or two more repetitions with the same weight.
- Add sets: tack on one extra set of an exercise.
- Shorten rest periods: cut 10 to 15 seconds from your break between sets.
Change only one variable at a time. If you added weight this week, don’t also cut your rest periods. Small, consistent increases are safer and more sustainable than big jumps that leave you too sore to train again for a week.
Daily Movement That Counts
Formal workouts aren’t the only way to be active. Everything you do that isn’t sleeping, eating, or structured exercise still burns energy. Walking to work, taking the stairs, doing yard work, cleaning the house, even fidgeting at your desk all contribute. Researchers call this non-exercise activity thermogenesis, and it accounts for the vast majority of your non-resting energy expenditure. For many people, increasing daily movement (parking farther away, standing while on the phone, walking during lunch) can be just as impactful as adding a gym session, especially early on.
Putting It All Together
A balanced weekly plan doesn’t have to be complicated. One straightforward approach: walk briskly for 30 minutes on five days (that covers your 150 minutes of moderate cardio), and do a bodyweight strength routine on two of those days or on separate days. Add five minutes of dynamic stretching before each session and a few minutes of static stretching afterward. If you prefer vigorous activity, three 25-minute jogs plus two strength sessions achieves the same targets in less total time.
If you have a chronic medical condition, a screening tool called the PAR-Q+ can help you determine whether you need medical clearance before starting. It’s a short set of seven questions about your health history. If you answer no to all of them, you’re generally cleared to begin following standard activity guidelines. Answering yes to any question doesn’t mean you can’t exercise; it just means some additional screening can help you find the safest starting point.
