How to Start Exercising: Walking, Strength, and Your First Week
Short on time for exercise? Learn why walking and strength training matter, then use a beginner schedule that separates your first week from longer-term activity targets.
You know you need more exercise. But work leaves you tired, and joining a gym would add another commitment. Is walking enough? Do you need strength training too?
If you are mostly inactive, start by making room for walking and add strength training on two days each week. Short walks during desk work are another useful addition.
This guide uses exercise research and WHO guidance to help you build a schedule. It separates a manageable first week from the amount of activity to work toward.
Separate your starting point from your weekly target
WHO recommends 150–300 minutes of moderate aerobic activity, or 75–150 minutes of vigorous activity, plus muscle-strengthening activity on at least two days each week. It also emphasizes that some activity is better than none. WHO physical activity guidelines
If you currently do very little, start with a slot you can use, such as a ten-minute lunch walk. Review what you manage and how you feel before adding more. If you already walk regularly, strength training may be the missing piece to prioritize.
1. Add walking: put ten minutes into your lunch break
Walking needs little preparation. As it becomes comfortable, a pace at which you can talk but not sing is a useful guide to moderate intensity. CDC intensity guidance
Aerobic exercise has trial evidence for reducing blood pressure. In Edwards and colleagues’ analysis of 270 trials, aerobic training lowered systolic pressure—the upper number—by about 4.5 mmHg compared with non-exercising controls. This average covers varied programs and participants. It is not the predicted effect of a ten-minute lunch walk. Exercise and blood pressure: Edwards et al., 2023
For longer-term health, a large analysis of follow-up studies found lower mortality associated with more non-occupational physical activity. The largest differences occurred when moving from little activity toward more. These observational findings cannot isolate exercise as the sole cause. Physical activity and long-term risk: Garcia et al., 2023
Make the plan specific: “After clearing lunch on Monday, Wednesday, and Friday, I will walk around the block for ten minutes.” If evenings leave you exhausted, use lunch. If it rains, choose somewhere indoors.
Shorten the walk when necessary. At first, you are finding a place for movement in your actual schedule.
2. Reserve two days for strength training
Once you have a walking plan, make room for strengthening the major muscle groups. Begin with a load that lets you practice the movements.
Currier and colleagues analyzed 178 trials of strength and 119 of muscle growth. Many training prescriptions improved outcomes compared with no exercise. Heavier loads favored strength gains, but this does not mean beginners need to start there. Resistance-training comparisons: Currier et al., 2023
Possible home exercises include standing up from a chair, wall push-ups, and resistance-band rows. If you are unsure how to cover your legs, back, chest, trunk, and other major muscle groups, an introductory coaching session can help you choose.
The CDC describes eight to twelve repetitions as a set. Try one set with a manageable load and check whether you can maintain the movement. These are planning examples, not a complete program suited to every reader. CDC strength-training guidance
Reserve two slots, such as before dinner on Tuesday and Saturday. Keep a short list of the chosen exercises so you do not need to invent a new session each time.
3. Break up desk work with short walks
Alongside planned exercise, add interruptions to long sitting periods. Working from home may offer opportunities to leave the desk between tasks.
Dunstan and colleagues compared uninterrupted sitting with two-minute walking breaks every twenty minutes in 19 adults with overweight or obesity. Walking reduced glucose and insulin responses after a test drink. This was a one-day experiment, not evidence of long-term disease prevention. Sitting-break trial: Dunstan et al., 2012
The study’s interval is not a universal requirement. Choose workable breaks, such as walking to get water between meetings. Add them alongside your weekly aerobic activity and strength work.
A beginner’s first-week schedule
This is an example, not a tested intervention. It provides thirty minutes of planned walking, which is still below WHO’s 150-minute moderate-activity target. The first week checks whether the schedule fits.
| Day | Plan |
|---|---|
| Monday, Wednesday, Friday | Walk for ten minutes after clearing lunch |
| Tuesday, Saturday | Practice your selected strength exercises before dinner |
| Desk-work days | Leave the desk for short walks between tasks |
| Sunday | Review walking minutes, strength sessions, fatigue, and pain |
If the week feels manageable, gradually add walking time or another day. A later schedule could distribute 150 minutes as thirty minutes of moderate walking on five days. How you build toward that depends on your fitness and circumstances.
When sessions keep falling through, inspect the timing. Move an evening walk to lunch, or choose a slot that needs less preparation. The habit-planning guide offers examples.
Common questions
Does a five-minute walk count?
WHO emphasizes that some movement is better than none. Five minutes is a starting point, not the equivalent of a full weekly activity target. Look for opportunities to build on it.
Do I need a gym for strength training?
Body weight and resistance bands are options. Focus on selecting suitable movements and loads that cover the major muscle groups.
Must I exercise every day?
Begin by choosing specific days. This sample distributes walking and strength work across the week; a daily streak is not the goal.
What if I have pain or a medical condition?
Ask a clinician about appropriate activities and intensity. Stop and seek medical help for chest pain or severe breathlessness rather than trying to finish a target. NIDDK activity guidance
Your next step: schedule the next ten-minute walk
Build walking into your week, add two strength-training days, and interrupt long sitting periods. Keep the first week separate from your longer-term target.
Put one lunch walk into your calendar. After trying it, choose the days on which you can repeat it.
