While she tried working out at the campus rec center and a few Les Mills pre-choreographed group fitness classes, nothing stuck. Then, her relationship to her body started to change.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">&#8220;A lot of my body image issues really bubbled in college,&#8221; she said.<\/p>\n<p><img alt=\"Morgan Kline\" loading=\"lazy\" width=\"960\" height=\"720\" decoding=\"async\" data-nimg=\"1\" class=\"rounded-lg\" style=\"color:transparent\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2026\/08\/https:\/\/media.zenfs.com\/en\/business_insider_consolidated_articles_886\/2ebc18bd6862a88a947711c91956f1.jpeg\"\/><\/p>\n<p>Kline cofounded Burn Boot Camp, which now has over 400 locations across the US.Morgan Kline<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Just a few years after graduating, Kline cofounded <a data-ylk=\"slk:Burn Boot Camp;elm:context_link;itc:0;sec:content-canvas;\" data-yga=\"{&quot;yLinkElement&quot;:&quot;link&quot;,&quot;yLinkElementType&quot;:&quot;article_link&quot;}\" href=\"https:\/\/www.businessinsider.com\/burn-boot-camp-couple-grew-fitness-franchise-2021-3?utm_medium=referral&amp;utm_source=yahoocom&amp;utm_medium=syndication&amp;utm_source=yahoo\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">Burn Boot Camp<\/a>, a fitness franchise, with her husband, Devan in 2012.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">She said she no longer works out solely for appearances, which &#8220;can get really exhausting&#8221; as a motivator. Burn Boot Camp studios don&#8217;t include mirrors. While gym-goers may use them to check their form in other workout classes, Kline believes trainers should be the ones to give feedback on safe movements, and personally finds mirrors to be too distracting.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Now, her workouts are &#8220;about doing hard things every single day, making fitness a priority, and setting healthy examples for your children,&#8221; Kline said. &#8220;It&#8217;s so when I am a grandma, I can still pick up my grandkids. Those are the things that I&#8217;m training for now.&#8221;<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Kline, who strength-trains about 4 to 5 times a week, shared a few habits she&#8217;s followed for over a decade that helped her consistently <a data-ylk=\"slk:build muscle;elm:context_link;itc:0;sec:content-canvas;\" data-yga=\"{&quot;yLinkElement&quot;:&quot;link&quot;,&quot;yLinkElementType&quot;:&quot;article_link&quot;}\" href=\"https:\/\/www.businessinsider.com\/build-muscle-fast-strength-training-expert-exercises-2026-4?utm_medium=referral&amp;utm_source=yahoocom&amp;utm_medium=syndication&amp;utm_source=yahoo\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">build muscle<\/a>.<\/p>\n<p>2 simple compound workouts target many muscle groups<img alt=\"Morgan Kline\" loading=\"lazy\" width=\"960\" height=\"720\" decoding=\"async\" data-nimg=\"1\" class=\"rounded-lg\" style=\"color:transparent\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2026\/08\/https:\/\/media.zenfs.com\/en\/business_insider_consolidated_articles_886\/fe6d27ccc4da617288b1905855a4de.jpeg\"\/><\/p>\n<p>Kline works on going heavier on her deadlifts and increasing her pull-up rep counts.Morgan Kline<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Compound exercises target multiple muscle groups at once.

As a mother of three kids \u2014 ages 10, 8, and 6 \u2014 she said deadlifts help make it easier to &#8220;lift them up, or lift up things at the house that I don&#8217;t need my husband for.&#8221;<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">As for pull-ups, she finds them valuable because they&#8217;re especially harder for women to do, as women typically carry less upper-body mass. &#8220;That&#8217;s something that I&#8217;m constantly trying to work on,&#8221; she said, as pull-ups build up muscles in her arms, shoulders, lats, and core.<\/p>\n<p>She keeps her protein-rich diet simple<img alt=\"Morgan Kline with son\" loading=\"lazy\" width=\"960\" height=\"720\" decoding=\"async\" data-nimg=\"1\" class=\"rounded-lg\" style=\"color:transparent\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2026\/08\/https:\/\/media.zenfs.com\/en\/business_insider_consolidated_articles_886\/c79915a233f47383696c48a070b9aa.jpeg\"\/><\/p>\n<p>Kline tries to include protein in every meal, including snacks.Morgan Kline<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">When it comes to nutrition, Kline knows that protein is a &#8220;hot topic&#8221; right now.

She also loves eggs and chicken sausage in the morning and uses plant-based protein powder in her smoothies.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Ultimately, she said her routines, which she&#8217;s kept for years, free her up to think about other things besides how her body looks. &#8220;I would be lying if I said I don&#8217;t have goals \u2014 we all want to look good because when we look good, we feel good,&#8221; she said.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">It&#8217;s just that she doesn&#8217;t want to focus on that all the time. &#8220;You&#8217;re constantly looking in the mirror and looking for value, whereas I&#8217;ve shifted my mindset to look for value in other ways in my life.&#8221;<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">If you enjoyed this story, be sure to follow <a data-ylk=\"slk:Business Insider;elm:context_link;itc:0;sec:content-canvas;\" data-yga=\"{&quot;yLinkElement&quot;:&quot;link&quot;,&quot;yLinkElementType&quot;:&quot;article_link&quot;}\" href=\"https:\/\/profiles.yahoo.com\/brands\/business-insider\/\" rel=\"nofollow noopener\" target=\"_blank\">Business Insider<\/a> on Yahoo.<\/p>\n","protected":false},"excerpt":{"rendered":"Morgan Kline cofounded Burn Boot Camp with her husband, Devan Kline, in 2012.
