اليوم كان عندي تمرين لكامل الجسم من النوع اللي يرفع النبض ويتحدى القوة والثبات في نفس الوقت. بدأت بـ 5 جولات على جهاز الرو لمدة 30 ثانية عشان أجهز أكبر عدد ممكن من العضلات قبل الأوزان. التمرين كان عبارة عن 5 حركات، وسويت 3 جولات من كل تمرين. هدفي كان من 10 إلى 12 عدة لكل حركة، ولكل جهة إذا كان التمرين أحادي الجانب. الشي اللي أحبه في تمارين كامل الجسم إنها تعطيني أكثر من فائدة في نفس الجلسة. أشتغل على القوة، التوازن، الثبات، اللياقة، والتناسق بين الجزء العلوي والسفلي من الجسم. صح التمارين المركبة
