Initial gains (2-4 weeks): Aerobic capacity and muscle gains can get better within this time, especially if you are new to exercise. You may notice that you have improved energy, mood, and sleep.
Between two and four weeks of regular exercise you will start to see measurable improvements in your strength and fitness. If weight loss is a goal and your exercise program is being complemented by healthy eating then you may start to see desirable changes in your weight.
After a month of regular exercise, you will be noticing improvements to your strength and fitness. ``You may be able to do more reps in weight training or slightly raise the load, or you're able to walk, jog or cycle a bit faster,'' Robergs says.

Visible Changes (4-8 weeks): More noticeable changes in body composition, such as weight loss or muscle definition, typically become evident within 4 to 8 weeks if you're following a balanced exercise routine and healthy eating habits.
Your Body. The embryo continues to implant in your uterus, burying itself deep within the endometrium. Some women have slight cramping and spotting during this week while implantation happens. They might mistake this for a period, especially because this is around the time their monthly period was due.
After a month of exercise:
Most of the improvements in strength and function are from more efficient nerve connections into the muscles, so that the firing patterns of your muscles is more selective and responsive. The blood vessels into the muscles have grown and become more efficient (angiogenesis).
After two to three months of consistent training, more substantial muscle size and strength changes become apparent. Muscles tend to appear fuller and more defined at this stage. It's crucial to progressively increase the resistance or weight lifted during this period to continue stimulating muscle growth.
There are several research-backed reasons why you might notice a slight weight gain after exercise. These include muscle gain, water retention, post-workout inflammation, supplement use, or even undigested food. In most cases, post-workout weight gain is temporary.
Stage 1: Fast weight loss
In the beginning, weight loss happens pretty rapidly. Over a period of 4-6 weeks, you'll likely see a noticeable difference in your body weight [1] — either on the scales or by the way your clothes fit.
It is possible to see toning in a month if you work out every day although most people see noticeable results within 6 to 8 weeks.
Muscle and Cardio
Noticeable changes (2-4 months): More noticeable changes typically occur within several months, including weight loss and muscle tone. Your genetics, muscle fiber makeup, and the quality of your workouts affect your strength if you are well-conditioned.
"In general, if you continue to consistently strength train and add in two to three days of zone two cardio workouts, plus proper fuelling, you can see healthy weight loss in four to six weeks", McKenzie says. But substantial weight loss (and fat loss) often takes much longer.
Your cardiovascular fitness will have increased significantly, and you'll likely notice changes in your body composition, including potential weight loss and improved muscle tone. Consistency is critical during this phase to continue building endurance and strength.
Muscle is denser (meaning a lot less fluffy) than fat, says Dr. Calabrese. Put another way, 10 pounds of muscle takes up a lot less space than 10 pounds of fat. So, as you start working out regularly and building strength, the new muscle you build may eventually weigh more than the fat you've burnt off.
It's normal to experience muscle swelling and soreness after novel or eccentric-heavy exercise for up to 24-72 hours. You should still be able to perform your daily activities during that time. Remember, this is a temporary phase, and your body will soon return to its normal state.
The answer, as always, is it depends. Some people might be able to see incredible results in such a short period of time, while others might need a little bit more time to make fundamental changes. What I can say for sure is that with the right approach, a 4-week body transformation is possible.
You'll know about this usually in the first couple of weeks, as you might notice quite a significant loss on the scales at this time. However, don't see this as setting the bar for yourself. A lot of the weight that you've lost so far will have come from the excess fluid that was in the body.
Are you fueling your body? “You have to have the right combination of diet and exercise,” he explains. “Some people aren't consuming the right amount or type of energy.” If you're trying to lose weight, you'll need to consume fewer calories than you're expending.
Typically, you can improve your cardiorespiratory or aerobic fitness in about 8 to 12 weeks of regular training. But you might see results sooner, at around 4 to 6 weeks. That's good news, considering that it may only take 2 to 3 weeks of inactivity to hurt your progress.
If you're exercising regularly and doing a mix of cardio and strength training, it's likely your body composition (ratio of muscle to fat) is changing for the better. “If the scale isn't moving, but your clothes fit better, and you feel stronger, that's a win,” Pelc Graca says.
However, exercising on an empty stomach will also cause you to lose lean muscle mass at the same time, which can hinder long-term weight loss. Exercising without eating first can cause dramatic shifts in your blood sugar, and when it drops quickly you can feel nauseous, light-headed or dizzy.
