How do you use relative intensity?

RI is defined as the weight used for X number of reps in relation to the maximum weight with which you can accomplish X number of reps. For example, suppose you can squat 225 pounds for an absolute maximum of 10 reps. Nonetheless, you are training with 205 pounds for sets of ten. You are achieving a RI of 205/225 = 91 percent.

The key to using relative intensity effectively is to understand how it works and how to adjust your program based on how you feel during each workout. If you can do more than six repetitions at absolute failure with good form, add weight to the bar. If you can't get past three reps, drop down to less weight or change modes. Don't worry about percentages; just keep adjusting the weights until you reach your desired level of intensity.

Here are some other examples using common exercises:

For bench press, let's say you can lift 90 pounds for eight reps. That would be considered very heavy exercise intensity. At this point, you should be able to complete two more reps with 100 pounds. So, your new RI is 90/100 = 90 percent.

If you can only lift 70 pounds for four reps, then the exercise is too easy. Drop the weight to now where you can lift 80 pounds for five reps. Your new RI is 70/80 = 87.5 percent.

What is the intensity of strength?

The level of resistance utilized is known as intensity, and it is generally stated as a percentage of the one-repetition maximum (percent 1-RM) for a certain lift. Another approach to express intensity is to state the maximum number of repetitions that may be accomplished for a certain lift. For example, an exercise that can be done 20 times maximum would be considered moderately difficult while one able to be performed only once is described as very hard.

Intensity is a key factor in determining how much muscle fiber stimulation and growth occurs during strength training. Intense exercises stimulate more muscle fibers and thus lead to greater growth than less intense ones. However, too much intensity at any time will cause injury because large muscle groups are being used without sufficient rest between sets.

There are two ways to increase the intensity of your strength training sessions: by changing the weight you lift or by adding more repetitions to current lifts. Either method will bring about significant changes in your muscles over time.

Changing the Weight You Lift

As you gain experience with weight lifting, you will find that you become stronger able to use heavier weights then when you first started out. This is because your body gets better at handling heavy loads over time. So, by keeping the weight constant but increasing the number of repetitions you can boost your intensity significantly.

How does volume relate to intensity?

Volume and intensity are linked; as intensity increases, the volume that a lifter can perform must decrease. By definition, a lifter cannot perform their one-rep personal record for many sets or reps. In contrast, when intensity decreases, volume must rise to give enough stress on the lifter. For example, if a person's one-repetition maximum (1RM) is 200 pounds, then they could probably do three 10-pound lifts before passing out from exhaustion. However, if their 1RM was reduced to 100 pounds, then they would need to lift 30 times to reach the same level of fatigue.

As another example, assume that someone can squat 150 pounds. They might be able to complete six repetitions at this weight without any problem. If the load were increased to 175 pounds, then they would have to reduce the number of repetitions they performed to four in order to achieve the same level of fatigue. Finally, if the person's goal was to improve their performance and they wanted to go for their one-rep max, then they would have to reduce the amount they loaded themselves so that they could sustain one full repetition over time.

In general, volume is simply the amount of work you do during a given period of time. So, the more work you can do in a given amount of time, the more volume you can handle simultaneously or in succession. Intensity is how hard you push yourself during a set or rep range.

How do you establish the rate of perceived exertion?

You choose a value between 1 and 10 based on muscular tiredness, higher heart rate, and increased pace of breathing to get your RPE. The greater the number, the more strenuous the workout. An RPE of 1 is considered to be slightly above rest, with little exertion, whereas an RPE of 10 is considered to be peak effort. Most people can maintain an RPE between 6 and 9.

The best way to establish the rate of perceived exertion is by using a scale that measures how hard you are working out. There are many different scales available, but the most common one is called the Borg Scale. It works by measuring your maximum heart rate (which can be found by taking your age times 0.65 if you are over 40). Then you measure how hard you are working out by comparing it to this maximum heart rate. If you are working at a lower intensity than this maximum level, then you should feel exhausted and need to slow down or stop exercising. When you reach this maximum heart rate, you will not be able to maintain this pace for more than 10 minutes, so you should start reducing your exercise load gradually until you return to a lower intensity.

On the Borg Scale, 1 is equivalent to very light activity, while 10 is equivalent to maximal effort. So, the harder you work, the higher number you will see on the scale. You can also estimate the amount of effort you are putting in by comparing your own performance to others who have done similar exercises before you.
