Can you help me to correct my text?
Today I'm going to give you a brief and effective routine that <s>it</s> will provide you a strong and CHISELED <s>aesthetics </s>chest.
You could <s>alter</s> INCREASE the number of reps, but it's important that you take your time, respect the process, <s>respect the time of work </s>and rest IN-BETWEEN <s>during </s>every set. So, in case <s>of</s> you can't complete the total number of reps in <s>on</s> every set, you can reduce them, but bear in mind that you will have to compensate for this. <s>I mean, that you will have to</s> maintain<em>ING</em> the posture until <s>it </s>the time is finished <s>the set</s>.
<s>I promise you that</s> your chest, triceps and abs are going to improve CONSIDERABLY<s> (¿or substantially?)</s> if you practice this routine 2 or 3 times a week. Moreover, you WILL only require a bench, bed or a chair and of course, the floor, to carry out this routine<s> satisfactorily</s>. There are no <s>not</s> excuses.
Before we start<s>ing</s> I want<s> that</s> you TO PROMISE <s>compromise with</s> yourself THAT YOU WILL <s>to </s>finish this routine once you START <s>starting</s>, no matter what. I'm sure that after A <s>once </s>month and a half you will be <s>really </s>satisfied with this effective and simple routine. WITH THIS IN MIND <s>Mindful of this</s>, let's get started!
