URoslyn uneminyaka engu-36 ubudala, unesisindo esingamakhilogremu angu-74, ubude bungamasentimitha angu-165, futhi unamafutha omzimba angu-35%. Uyise wahlaselwa isifo senhliziyo eneminyaka engu-68 ubudala futhi umfowabo wenziwa i-angioplasty eneminyaka engu-40. Bobabili bayaphila futhi banempilo. Izilinganiso zakhe zamakhemikhali egazi zilinganisa i-cholesterol ephelele ku-195 mg% ne-HDL cholesterol ku-42 mg%. Ushukela wakhe wegazi ongadlile u-105% mg%. URoslyn uhlala ehleli futhi akakaze ahlanganyele esimisweni sokuzivivinya kusukela ekolishi. Cabangani ngohlelo olufanele lokuzivocavoca oluzosiza uRoslyn ukuba athuthukise ukuqina komzimba wakhe. Qiniseka ukuthi ubala ibanga lokushaya kwenhliziyo elihlosiwe ne-RPE ehambisanayo.
Singasinikeza isimiso sokuvivinya umzimba ngokombono we-FITT: imvamisa, ukuqina, isikhathi, nohlobo. Ngokuqondene nobuningi, kufanele sihlose izinsuku ezingu-3-5 ngesonto, uma ziphakeme ngcono ukuthuthuka kokufaneleka kwe-CR. Ngokuqondene nokuqina, sifuna ukuzama ukuthola i-HRR (i-heart rate recovery) engamaphesenti angu-60 kuya kwangu-90 noma kuphi phakathi kuka-4 kuya ku-8 RPE (izinga lomzamo owaziwayo). Njengoba uRoslyn eneminyaka engu-36 ubudala, isilinganiso sakhe sokushaya kwenhliziyo esiphezulu esilindelekile singu-184bpm, futhi sitshelwa ukuthi i-RHR (Resting Heart Rate) yakhe ingu-64bpm. Ngakho-ke, sihlose ukuthi izinga lokushaya kwenhliziyo elihlosiwe libe phakathi kuka-136 BPM no-172 BPM. Ngokuqondene nesikhathi, ubude besikhathi buyehluka kuye ngamandla, kodwa ngokufanelekile, sifuna ukuzivocavoca okungenani imizuzu engu-20 futhi okungenani ihora. Ngokuqondene nohlobo lokuvivinya umzimba, singahlola izinketho ezikhona futhi ezenzekayo ukuba uRoslyn azenze, bese sikhetha phakathi kokuvivinya umzimba okuthwala isisindo (njengokuhamba noma ukugijima) nokuvivinya umzimba okungathwali isisindo njengokubhukuda noma ukugwedla. Enye into okufanele uyicabangele ukuthi uRoslyn uhlala phansi, futhi kungase kudingeke ukuba athuthukele kancane kancane ekuzivivinyeni okunamandla ngokwengeziwe. Uhlelo lokuzivivinya lukaRoslyn lungase luqale ngokuvivinya umzimba ngesilinganiso esiphakathi imizuzu engu-30 ngosuku, kathathu ngesonto (ngoMsombuluko, ngoLwesithathu nangoLwesihlanu). Njengoba eqala ukujwayela ukuvivinya umzimba, sifuna ukuqhubekela phambili ekuvivinyweni okunamandla ngokwengeziwe. Ngokusho kukaDavid P. Swain, ukuvivinya umzimba okunamandla kungaphumela "ezinzuzweni eziningi kakhulu kunokuvivinya umzimba okunesilinganiso esiphakathi", ezihlanganisa kodwa ezingagcini ekuthuthukisweni okukhulu kokuqina komzimba nokwehliswa okukhulu kwengozi yesifo senhliziyo. Ngakho, singanezela ezinye izinsuku ezimbili zokuvivinya umzimba okunamandla kukaRoslyn, njengokugijima imizuzu engu-20 ngoLwesibili nangoLwesine. Esinye isici esibalulekile okufanele sisicabangele isisusa, esingamsiza uRoslyn ukuba asigcine ngokushintsha izindlela zakhe zokuvivinya umzimba ukuze agcine isithakazelo. Ngokwesibonelo, singashintshanisa ukugijima nokuhamba ngebhayisikili, noma ukuhamba ngezinyawo ezindaweni ezinezintaba.
