全球暢銷書《一分鐘經理人》作者肯．布蘭查（Ken Blanchard）這次「棄文從武」，把加強團隊領導力的方法運用在健身訓練，與合著作者也是一名健身教練Tim Kearin，提出一個專業有效的健康建議，讓讀者培養持之以恆的鍛鍊，增強健康體魄，面對每天的挑戰。

現代人越來越注重健康，而不少人選擇到健身中心運動，卻無法持之以恆。這現象是作者口中所稱的「承諾和興趣之間的差異」。『興趣驅動的鍛鍊者』，會為不運動找出種種的藉口，例如太好忙了、外面在下雨、好疲累等等，而『承諾驅動的鍛鍊者』，即使遇到任何突發情況，都阻止不了他們運動的動力，總是實事求是地遵守承諾。

在《Fit at Last》一書中，兩位學有專精的作家，一起鼓勵人們將運動健身從興趣轉變為承諾。肯．布蘭查向讀者分享自己在進行健身計畫時遭受一波多折的故事，以及他最後如何憑著組織管理的商業策略，讓自己成功又有效地完成整個鍛鍊課程，讓他岌岌可危的健康獲得改善。

身為肯．布蘭查的私人教練的Tim Kearin的健身教練，也在書中提供許多專業的健康建議以及訓練知識。他們兩人強調，健身難以獨自一人完成，當然也不是每個人都能雇用一名教練，因此，他們告訴我們如何建立一個非正式的小組，幫助自己做到健身計畫。

肯．布蘭查將管理的座右銘得宜地套用於健身鍛鍊。他說：「沒有失敗，因為人們不知道要做什麼。失敗，是因為人們知道而不去做。」這本書提出的鍛鍊工具，讓我們將興趣轉變成承諾，勇敢建立第一步，幫助身體越來越健康。
