Your last InBody scan gave you a score of 72. You know that is “good” but not great. You want to be at 85 by the end of the year. The question is \u2014 what actually moves the number?<\/p>\n\n\n\n

The InBody Score is a single-number summary of your body composition, on a scale where 70 is average for adults, 80 is athletic, and 90+ is elite. It is calculated from your fat-free mass, body fat percentage, and muscle distribution. The full explainer post covers what each range means<\/a>. This post is different \u2014 it is a 90-day playbook for actually raising your score, based on the levers that genuinely move it.<\/p>\n\n\n\n

The two inputs that drive your InBody Score<\/h2>\n\n\n\n

The score formula is dominated by two body composition variables:<\/p>\n\n\n\n

    \n
  1. Skeletal muscle mass<\/strong> relative to your height and gender (higher = better)<\/li>\n\n\n\n
  2. Body fat percentage<\/strong> relative to your gender and age (closer to athletic range = better)<\/li>\n<\/ol>\n\n\n\n

    A third variable \u2014 segmental muscle balance \u2014 modifies the score modestly. If your left arm has significantly less muscle than your right (common in right-handed people), the score takes a small hit.<\/p>\n\n\n\n

    The implication: to raise your InBody Score, you must build skeletal muscle AND reduce excess body fat. Doing only one almost always underdelivers. The biggest mistake people make: they try to “diet down” their score upward and end up losing both fat AND muscle, so the score barely moves.<\/strong><\/p>\n\n\n\n

    How fast can the InBody Score actually rise?<\/h2>\n\n\n\n

    Realistic 90-day expectations, holding everything else constant:<\/p>\n\n\n\n

    Starting Score<\/th>Realistic 90-day gain<\/th>Realistic 6-month gain<\/th><\/tr><\/thead>
    50\u201360 (very low)<\/td>+8\u201312 points<\/td>+15\u201320 points<\/td><\/tr>
    60\u201370 (below average)<\/td>+5\u20138 points<\/td>+10\u201315 points<\/td><\/tr>
    70\u201380 (average\u2013good)<\/td>+3\u20135 points<\/td>+7\u201310 points<\/td><\/tr>
    80\u201390 (athletic)<\/td>+1\u20133 points<\/td>+3\u20136 points<\/td><\/tr>
    90+ (elite)<\/td>+0.5\u20131 point<\/td>+1\u20132 points<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    The lower your starting point, the faster the score moves \u2014 because beginners gain muscle quickly (newbie gains) and lose fat quickly. Once you are above 80, every additional point requires meaningfully harder work.<\/p>\n\n\n\n

    The 90-day playbook<\/h2>\n\n\n\n

    Week 1: Establish the baseline<\/h3>\n\n\n\n
      \n
    1. Get a baseline InBody scan<\/a>. Note: score, skeletal muscle mass (in kg), body fat percentage, body fat mass (in kg), segmental muscle balance, ECW\/TBW ratio.<\/li>\n\n\n\n
    2. Tape-measure 5 sites: waist (at navel), chest (across nipples), upper arm (relaxed), thigh (mid), hip (widest).<\/li>\n\n\n\n
    3. Photo: same lighting, same time of morning, three angles. You will repeat this Day 30, 60, 90.<\/li>\n\n\n\n
    4. Honest food log for 5 days \u2014 average daily protein grams and total calories. This is the most important number you will calculate.<\/li>\n<\/ol>\n\n\n\n
