The physiological impacts on your body Any improvements you've seen with your blood pressure, cholesterol levels, and blood sugar may diminish. You may experience some weight gain. If you've been strength training, the gains in muscle size, strength, and endurance you worked so hard for will taper off.
Yes, if you stop working out for 3-4 months, you are likely to lose some muscle strength. This process is known as ``detraining.'' The extent of strength loss can vary based on several factors, including:
To fully regain and potentially surpass your previous levels, it may take several months of regular training, typically around three to four months. The rate of improvement can vary based on factors like your initial fitness level and the intensity of your workouts.
So, for example, if your time off was six months, it could take only two to three months to regain the strength and size you lost. If you had three months off, it would take about 6 weeks. This rule only works on a scale of months, not years, so the rule breaks down if your time off was longer than six months or so.
You may notice that you have improved energy, mood, and sleep. 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.
Visible muscle loss should not occur with training breaks even as long as two weeks. Measurable reductions in muscle size have been documented in studies after detraining periods of four weeks, although the reduction in muscle size appears to occur faster than reductions in muscle strength and function.
Noticeable Changes (Months 2-3): After two to three months of consistent training, you'll likely start seeing more significant muscle size and strength changes. At this time, many people notice that their muscles appear fuller and more defined.
For the majority of people, it takes roughly 130 quality hours to get fit. A lot of people ask me where I got that number. It's equivalent of training hard, an hour a day, 5 days a week, for 6 months. Your hours can't be half-ass hours, either.
So if you lose 1lb (0.45kg) a week you could hope to reduce your waistline by an inch after four weeks. Dieticians advise that if you eat 500 calories less than your daily requirement you will lose about 1lb every seven days (expect some variation from person to person).
"A lot of people feel and look less tight and toned when they stop working out," he explains. "It's more of a cosmetic thing." When you don't work out regularly, your body composition starts to change. With little physical activity, muscle cells shrink.

As muscle cells get smaller, fat cells tend to get bigger. After all, the muscles aren't working hard enough to burn away calories. This can lead to weight gain as soon as 14 days (or earlier) once you stop exercising, according to Men's Journal.
Studies have linked being inactive with being overweight and obese, type 2 diabetes, some types of cancer, and early death.
A sedentary or inactive lifestyle.
They will become smaller and weaker. If you've been doing high intensity exercise or weight training, you'll find a reduction in your muscular endurance. A detraining period of 12 weeks results in decreased muscle mass and muscular strength, although the muscles can return to pretraining levels.
To lose weight effectively and safely, aiming to lose 1 to 2 pounds (lbs) per week may be best. This means that losing 20 lbs may take 10 to 20 weeks. To lose weight, people will likely need to follow a healthy diet and get regular exercise. Some popular diets are effective initially but challenging to maintain.
Glatt said that as long as you train consistently, it usually takes about half the break length to get back to your previous fitness level—which is consistent with the new study's findings. “For instance, a six-week break might require three weeks of training to regain prior levels of strength and size,” he said.
In fact, it could take over 12 weeks to really start to see any major differences. However, from around two weeks after stopping exercising you could begin to see some very gradual muscle tissue loss, also known as atrophy. Over time this could lead to lower strength, poorer balance and an increased risk of injury.
Although adequate protein throughout the day is necessary, extra strength training is what leads to muscle growth — not extra protein intake. You can't build muscle without the exercise to go with it. The body can't store protein, so once its needs are met, any extra protein is used for energy or stored as fat.
Regular exercise will provide you with more significant fitness and lifestyle benefits over time. Individuals can vary however, you can see differences after 6 to 8 weeks.
