The most difficult training to complete is the one that is done to failure and everyone thinks it will provide the best results. However, studies indicate a different result.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Researchers tend to get comparable <\/span><strong><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/33497853\/?utm_source=chatgpt.com\" rel=\"nofollow noopener\" target=\"_blank\">muscle gains<\/a><\/strong><span style=\"font-weight: 400;\"> by comparing the sets that are taken to failure with sets that end a bit short. The disparity is in the price. Going to failure leads to a lot of fatigue, which accumulates.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">The consequences of failing to succeed on each set:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">For days, you&#8217;re extremely achy.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">You are not recovered, which makes for poorer workouts.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">You&#8217;re wanting to quit the last reps, stress on joints and tendons.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">You are tired in everyday life, at work or in your home.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In the long term, you may lose motivation.<\/span><\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">The reps that count the most are the last few reps before failure; they may or may not be the most useful. Clamping and stopping at 1 or 2 RIR results in most benefits with minimal damage.<\/span><\/p>\n<h2 style=\"text-align: justify;\"><b>The basics of judging your RIR<\/b><\/h2>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">The difficult part is at the beginning. A lot of beginners guess incorrectly. They think they are at 2 RIR, when they actually could do 5 more. This is normal and will get better the more you practice.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Here are some tips:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Watch your speed. If a significant decrease in reps occurs, you&#8217;re approaching failure.

Now and then progress to a safe exercise to failure, such as a machine press or leg press,s to familiarize yourself with how it feels to fail.

This is because when you train with 1-2 reps in reserve, you will get results without being as fatigued, with a lower amount of joint stress, and in a shorter time to recover. When you add in the simplicity of some speed awareness, you can more easily judge your effort.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">For your next training session, do the following: finish each set when you have one or two reps remaining, in which case you are in the zone.
