Exercise Basics: Cardio, Strength, Mobility, and How to Start
Exercise includes structured physical activity performed to improve or maintain fitness, health or physical function. A well-rounded routine usually includes aerobic activity, muscle-strengthening work and enough movement variety to support mobility and daily function.
The Main Types of Exercise
- Aerobic exercise: brisk walking, cycling, swimming, jogging, rowing and dancing improve cardiorespiratory fitness.
- Strength training: body-weight exercise, machines, resistance bands and free weights improve muscular strength and can help maintain lean mass and bone health.
- Mobility and flexibility: controlled range-of-motion work and stretching can support movement quality and comfort.
- Balance and multicomponent activity: particularly useful as people age or when balance is a specific goal.
How Much Exercise Do Adults Need?
Singapore’s Physical Activity Guidelines recommend about 150 to 300 minutes of moderate-intensity aerobic activity per week and muscle-strengthening activity on at least 2 days per week. Those minutes can be accumulated across the week rather than completed in one long session.
How to Judge Intensity
At moderate intensity, you should be breathing harder than normal but still able to speak in short sentences. Vigorous activity makes conversation more difficult. Heart-rate targets can be useful for some people, but the talk test is a simple practical option.
If You Are New to Exercise
- Choose an activity you can perform comfortably and safely.
- Start with a manageable amount—sometimes 10 to 20 minutes is enough.
- Repeat it consistently before increasing difficulty.
- Add time first, then gradually add pace, resistance, hills or more challenging movements.
- Include recovery and easier days.
Do You Need HIIT?
No. High-intensity interval training can be useful for experienced exercisers or people seeking a time-efficient vigorous workout, but it is not required for health or fitness. People coming from inactivity should establish a base of regular aerobic activity first.

Do You Need a Gym?
No. Walking, stairs, home body-weight exercise, resistance bands, cycling and many recreational activities can all contribute to fitness. Equipment can be useful, but consistency and appropriate progression matter more than owning a particular product.

Stop for Concerning Symptoms
Stop exercise and seek appropriate medical attention for chest pain or pressure, fainting, severe or unusual shortness of breath, new neurological symptoms, or other concerning symptoms. If you have known heart, lung or metabolic disease or significant exercise limitations, individualized guidance may be appropriate before vigorous exercise.
