Choosing a Manageable Intensity When You First Start Exercising
Start with numbers, not motivation
The most common mistake when starting exercise is pushing yourself to run for an hour from day one. Think of the first 2 weeks not as a time to get results, but as a time to help your body adapt to exercise. At this stage, finishing while you feel you could do just a little more is actually the secret to keeping it going.

The easiest way to judge intensity by speaking
You can measure intensity even without a heart rate monitor. A good aerobic intensity is when you can have a short conversation with the person next to you while exercising, but singing would be difficult. If you are so out of breath that you cannot say a full sentence without stopping, it is too intense, so reduce your speed by 20 percent.
- Conversation and singing are both easy: too light, increase by 5~10 percent
- Conversation is possible but singing is hard: appropriate, keep it as is
- You gasp and cannot finish a sentence smoothly: too intense, slow down
A practical plan for the first 4 weeks
- Days 1~2: brisk walk for 20 minutes, then do 5 minutes of light stretching
- Days 3~7: increase brisk walking to 30 minutes and do it 3 times a week
- Week 2: while walking, repeat 1 minute of light jogging and 3 minutes of walking 5 times
- Week 3: add 2 sets of 10 bodyweight squats and 2 sets of 8 knee push-ups
- Week 4: increase to 3 sets and extend aerobic exercise to 35 minutes
For strength training, learn form before chasing reps
For squats or push-ups, learn the correct form before increasing weight or reps. If the last 2 reps out of 10 feel slightly hard, the weight is appropriate. If even the final rep feels too easy or your form breaks down, adjust the reps and weight. Rest 60~90 seconds between sets for each exercise.
| Category | Week 1 | Week 4 |
|---|---|---|
| Aerobic exercise | Walking 20~30 minutes | Walking and running 35 minutes |
| Strength training | None | 3 sets of squats and push-ups |
| Frequency | 3 times a week | 4 times a week |
| Rest days | 4 days a week | 3 days a week |
Include rest days in your plan
For beginners, recovery is just as important as exercise. Do not train the same body part hard two days in a row, and the day after strength training, choose light walking or rest. Mild soreness the day after exercise is normal, but if it lasts for several days or only one joint hurts with a sharp, stabbing pain, lower the intensity and focus on recovery.
If you experience chest pain, dizziness, or severe shortness of breath during exercise, or if you have an existing medical condition, consult a medical professional before starting.
Beginners should record how hard exercise feels as a number
When you first start exercising, intensity control matters more than motivation. For aerobic exercise, the standard is being able to talk but finding it hard to sing. For strength training, stop when the last 2 reps feel a little difficult.
The first 2 weeks are a period for helping your body adapt. Record how hard exercise felt on a scale of 1~10 on the days you work out, and build up slowly with the idea of increasing by only one level next time.
