Sanzo made a deep squat to really feel the stretch, before taking a seat on the leg press machine.<\/p>\n<p><a href=\"https:\/\/www.muscleandfitness.com\/flexonline\/training\/jay-cutlers-leg-press-workout-how-the-former-mr-olympia-built-massive-quads\/\" target=\"_blank\" rel=\"noopener nofollow\">The leg press<\/a>, like the squat, is a triple extension exercise that requires movement from the hip, knee, and ankle joints, and is a great way to further exhaust the quads, glutes, hamstrings, and calves, because the machine places less stress on the core than the free weight barbell squats, offering support and control to avoid injury by over working.<\/p>\n<p>Third-up was the hip thrust machine, including 5 sets with different rep ranges. Sanzo began with 12 reps and descended by 2 reps for each set, until she reached 6 reps. But for her fifth and final set, she went all out with a further 12 reps to force muscle hypertrophy and make great glute gains. Sanzo then rounded out her intense leg day with a twice-as-nice finisher, opting to superset two cable exercises. Part A was the <a href=\"https:\/\/www.youtube.com\/watch?v=ctaMoE_h2dU\" target=\"_blank\" rel=\"noopener nofollow\">kneeling cable bent-knee kickback<\/a>.<\/p>\n<p>To execute this move, the blonde bombshell faced the cable station and kneeled on a seat, using its inclined back rest for support. As Sanzo kicked-back Father time, she hit the glutes, hamstrings, calves, and core. For Part B, the fitness coach got vertical and positioned herself side-on to the cable station, executing the <a href=\"https:\/\/www.muscleandfitness.com\/exercise\/workouts\/abs-and-core-exercises\/standing-hip-abduction\/\" target=\"_blank\" rel=\"noopener nofollow\">standing dumbbell hip abduction<\/a>, in order to shape the outer hips while further taxing her glutes and thighs.<\/p>\n<p>\u201cLooking absolutely stunning as always,\u201d wrote one impressed follower. \u201cI\u2019ve been following you for years. Your consistency is truly inspiring,\u201d commented another fan. \u201cMay this be the best year yet my queen,\u201d wrote yet another.<\/p>\n<p>M&amp;F Hers can\u2019t wait to see what your year ahead in fitness looks like, Stephanie!<\/p>\n<p>To follow Stephanie Sanzo on Instagram, <a href=\"https:\/\/www.instagram.com\/stephaniesanzo\/\" target=\"_blank\" rel=\"noopener nofollow\">click here.<\/a>\u00a0<\/p>\n<p>\t\t<script async src=\"\/\/www.instagram.com\/embed.js\"><\/script><\/p>\n","protected":false},"excerpt":{"rendered":"Popular social media fitness influencer and inspirational personal trainer, Stephanie Sanzo has taken to Instagram to share her&hellip;\n","protected":false},"author":2,"featured_media":587013,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[62],"tags":[256783,256784,256785,337,97,26014,206532,256786,256787],"class_list":{"0":"post-587012","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-fitness","8":"tag-female-athlete","9":"tag-female-bodybuilding","10":"tag-fit-for-her","11":"tag-fitness","12":"tag-health","13":"tag-legs","14":"tag-legs-exercises","15":"tag-legs-workouts","16":"tag-mf-hers"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/587012","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=587012"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/587012\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/587013"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=587012"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=587012"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=587012"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
