So, the rule of leaving 2-3 days before working the same muscle again is already greatly erroneous. Eventually, it all boils down to how hard you trained a specific muscle or muscle group. Recovery can be measured in terms of intensity (is the muscle being trained a primary mover in a movement or a secondary) or time (48-72) hours.

Strength-Focused Recovery. If you're building strength, you can probably only do max effort workouts twice per week. Working at that intensity means you'll need 48-72 hours between sessions to recover. Remember, even if your muscles feel ready, your nervous system needs a break, too.

Determining Your Splits. There are many different ideas regarding the best weekly split for mass gain. Some experts say a five-day split in which you train separate muscle groups with high volume, therefore training each muscle group once a week, is the best plan. Yet others insist that a split in which you train each muscle group twice a week

The authors found that training two times per week led to greater muscle gains than training once a week. However, they did not find enough evidence to determine whether training three times per week had any added benefit. Therefore, you can allow three to four rest days between workouts for each muscle group.

Endurance Training. To increase muscular endurance as quickly as possible, the best rest period is 45 seconds to 2 minutes between sets. Classic endurance training (light-moderate weight, 15-20 reps) draws much of its energy from aerobic metabolism. This means your body burns carbs and fats in the presence of oxygen.

Training is merely the stimulus needed to produce muscular growth. Traditional workouts call for 3 workouts per week as the minimum and split routines of 4, 5 or even 6 weight training sessions per week as the maximum. The advice is to train using 3-to-5 exercises per body part, up to 15-to-20 sets per body part, and up to 1 1/2 to 2-hour

The answer is in regard to more than just drained sugar levels or lack of ATP in the muscle, but actually due to soreness. Studies show it takes 48 hours in most individuals for muscle soreness to reach its peak. If an individual attempts to train with weakened, sore muscles, the chance of injury goes way up. And you cannot train in the gym if

This type of training can be done from 2 to 4 times per week; a 24 hour rest period is sufficient. If you are more experienced and have a goal of increasing muscle size you should use an intensity of 75%-85% of your 1 repetition maximum for 6 to 12 repetitions and 3 to 5 sets.

What's more is that this soreness can hang around for a while. "Usually you don't actually feel sore until about 24 to 72 hours after your workout, and then this soreness can persist for up to three days," says Dr. Hedt. "This is why it's called delayed onset muscle soreness, or DOMS." (Related: No, Lactic Acid Buildup Isn't What Causes Muscle

Wait too long and the muscle returns back to a "normal" state and strength gains are slowed. ... Your muscles hit the supercompensation period in far less than a week and have started to return to normal by the time you train again. In this respect, fully body routines 2-3 times per week are going to produce strength gains much faster.

To increase strength and power, the best rest period is 2-5 minutes between sets. To increase hypertrophy (muscle growth), the best rest period is 30-90 seconds between sets. To increase muscular endurance, the best rest period is 30 seconds or less between sets. These rest periods are based on how the body produces the energy to perform work

48 Hours is the minimum time you should wait to train the same muscle group. If you are still sore you can train but it might be a good idea to reduce the work load on that muscle group. If you train without at least 48 hours rest you can increase the risk for injury and subject yourself to over training which will slow your progress.

The first few days after injury are called the acute phase. The first step in treating a grade 1 or 2 muscle strain in the acute phase is use of the R.I.C.E. method — rest, ice compression and elevation. Rest does not equal zero physical activity; however, exercise requiring the injured body part or daily tasks that increase pain should be avoided for the first few days after a muscle strain.

If you are sore that means your muscles arent ready to train again. Just rest until all soreness is gone and train again. Or if you have trained chest and triceps and chest is all sore, go train your back and biceps the next day. It really is that simple. Once again i am shocked by the stupid amount of people giving bad advice here.

48 Hours - aka every other day ex: Mon. Wed. Fri. Every 3 days. Here is my input on it: We know the muscle usually takes 48-72hrs to recover when trained with full muscle hypertrophy induction. However, the longer you wait after 72hrs, the less training effect you tend to keep with your last trained muscle group.

If you're going back, chest, legs, that'll be 3 days. Then later once you've gotten used to the workload, you can do those three days, then repeat it, and still have a rest day. I'm kind of new to working out regularly, and I was just wondering how much time should you give a muscle group to recover before exercising it again.
