For a 50-year-old, it is from 100 to 120bpm, while for a 60-year-old, it is from 96 to 112bpm.<\/p>\n<p class=\"mol-para-with-font\">Experts say it is difficult to judge whether someone is in Zone 2 based on breathing or effort alone, and recommend using a smartwatch or fitness tracker to stay in the right range.<\/p>\n<p class=\"mol-para-with-font\">Zone 2 exercises also include slow running, cycling, swimming, rowing machines or the stair stepper.<\/p>\n<p class=\"mol-para-with-font\">While many assume that running faster will help them to burn fat and lose more calories, some experts say this may not be correct.<\/p>\n<p class=\"mol-para-with-font\">Fat burning relies on a steady supply of oxygen, but, as the heart rate surges, there is less available, prompting the body to turn to other sources of fuel such as carbohydrates and proteins.<\/p>\n<p class=\"mol-para-with-font\">At Zone 2, however, this does not happen because the oxygen supply remains plentiful, potentially leading to greater fat burn.<\/p>\n<p class=\"mol-para-with-font\">Travers said: &#8216;When your heart rate increases, you&#8217;re not taking in as much oxygen. You can&#8217;t burn fat fast enough when you have less oxygen, so your body turns to other readily available energy sources.&#8217;<\/p>\n<div class=\"artSplitter mol-img-group\" style=\"\">\n<div class=\"mol-img\">\n<div class=\"image-wrap\"> <img loading=\"lazy\" decoding=\"async\" id=\"i-599cb78dff12664\" src=\"https:\/\/i.dailymail.co.uk\/1s\/2026\/04\/13\/17\/107861493-15729081-A_growing_number_of_fitness_experts_are_recommending_Zone_2_trai-a-1_1776099012909.jpg\" height=\"423\" width=\"634\" alt=\"A growing number of fitness experts are recommending Zone 2 training, saying it is best for boosting fat loss and fitness (stock image)\" class=\"blkBorder img-share\" style=\"max-width:100%\" loading=\"lazy\" \/> <\/div>\n<\/p><\/div>\n<p class=\"imageCaption\">A growing number of fitness experts are recommending Zone 2 training, saying it is best for boosting fat loss and fitness (stock image)<\/p>\n<\/div>\n<p class=\"mol-para-with-font\">Some experts also say that Zone 2 exercise can help to boost fitness gains.<\/p>\n<p class=\"mol-para-with-font\">High-intensity workouts often lead to rapid exhaustion, forcing people to stop earlier. But, in Zone 2 workouts, individuals can keep going for longer periods \u2014 providing, in some cases, that they don&#8217;t mind being overtaken by others.<\/p>\n<p class=\"mol-para-with-font\">Experts say that this added time helps to strengthen the heart muscle and boost mitochondria, the energy factory in cells, further boosting fitness.<\/p>\n<p class=\"mol-para-with-font\">Zone 2 training started to trend in 2025 after research emerged from University of Colorado exercise physiologist Dr Inigo San Millan, which suggested that cyclists who spent longer training at Zone 2 levels could go faster for longer.<\/p>\n<p class=\"mol-para-with-font\">Observations since then, however, have been less clear-cut on the benefits of Zone 2 cardio.<\/p>\n<p class=\"mol-para-with-font\">A <a style=\"font-weight: bold;\" class=\"\" rel=\"noreferrer noopener\" target=\"_blank\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/39390310\/\">2023 meta-analysis<\/a>\u00a0that tracked nearly 6,000 individuals who followed exercise plans found that those who did high-intensity interval training (HIIT) or sprint interval training (SIT) for at least four weeks had up to 3.9 times greater improvements in a key fitness measure than those who did endurance training (ET).<\/p>\n<p class=\"mol-para-with-font\">The paper defined ET as continuous exercise at a moderate intensity.
