오늘은 실내자전거(DVic)에 얽힌 사연을 풀어보려고 합니다. 우리를 사랑하는 분들이, 온 식구가 실내자전거를 가지고 우리가 살던 고양으로 올라왔습니다. 아마 4년 전의 일일 것입니다. 당시에 실내자전거를 조립해서 운동을 하려고 동네 당근에서 자전거를 하나 3만 원에 구입했는데, 차일피일 조립을 미루다가, 몇 년이 지나서 다시 울산으로 이사오면서 가지고 내려왔습니다.
결국 고양까지 가지고 왔던 분이 울산 우리 집에 와서 직접 조립하게 되었습니다. 조립하다말고 많이 낡은 뒷바퀴를 바꾸어야겠다고 시내 어느 자전거 상점에 나갔다가, 누군가가 주문하고 석 달이나 찾으러 오지 않은, 새로운 실내 전용바퀴를 구입해 왔습니다. 일반 자전거 바퀴와 달리 이 전용바퀴는 분진이 나오지 않으니 하나님이 준비해 놓으신 선물을 받은 셈입니다.
DVic(디빅) 실내자전거는 주로 가성비와 공간 활용성을 중시하는 홈트레이닝족 사이에서 알려진 브랜드입니다. 특히 게임이나 전용 앱과 연동하여 지루하지 않게 운동할 수 있는 기능을 강조하는 모델들이 많습니다. 전용 센서나 블루투스를 통해 스마트폰/태블릿의 운동 게임 앱과 연동할 수 있어, 화면 속 캐릭터와 함께 라이딩하며 재미있게 운동할 수 있습니다. 게다가 저소음 마그네틱 방식이니 자석의 자력을 이용한 저항 방식을 채택하여 층간소음 걱정이 거의 없습니다. 그러다 보니 늦은 밤이나 이른 아침에도 조용히 사용할 수 있습니다. 보통 8단계에서 많게는 14단계까지 강도 조절이 가능하여, 가벼운 유산소 운동부터 고강도 근력 운동까지 조절할 수 있습니다.(이 문단에 올린 정보는 제미나이 제공입니다)
어얼리 어답터이니 데스크탑을 켜고 운동 게임 앱과 연동해서, 화면 속 캐릭터와 함께 라이딩을 해 보지 않았을 리 없습니다. 그런데 한국나이 77세의 어르신(?)이 즐기기에는, 그것도 부러진 왼쪽 대퇴골 수술을 한 지 4개월 정도 지났을 때였으니, 신체적으로 우선 힘들었습니다. 또 그 나이의 교육을 받은 자로서는 화면 속 캐릭터가 앞바다 건너 어느 나라 사람이면 죽자 살자 따라잡으려고 하니 무리가 오는 것은 뻔합니다.
그래서 자전거를 타면서, 방법을 바꾸어 무료로 제공되는 로이드 존스의 설교(MLJ Trust) 파일을 듣기도 했지만, 돌 하나로 두 마리의 새를 잡는 일이나, 혼자서 단번에 토끼 두 마리를 잡는 일은 생각처럼 쉽지 않았습니다. 두 마리의 새도 날려 보내고, 두 마리의 토끼도 모두 놓칠 수밖에 없습니다.
그래서 결국 자전거를 서재에서 거실로 옮기고, 큰 화면의 TV 앞에서 씨비에스의 ‘새롭게 하소서’를 시청하면서, 손목에 있는 삼성헬스 시계에 실내자전거 타기를 실행하면 몇 초 후에 45분짜리 프로그램이 시작됩니다. 대체로 ‘새롭게 하소서’ 짧은 영상은 42분 내외니까 적당합니다.
라이딩은 5분 단위의 시간을 3분은 빠르게, 2분은 천천히 반복해서 달리면 약 220kcal의 에너지를 씁니다. 손목시계에 내장된 삼성헬스는 하루 1)기본 걷기는 6000보, 2)활동시간은 90분, 3)활동칼로리는 500kcal로 세팅되어 있으니 아침저녁으로 식후에 자전거를 타고, 게다가 점심 먹고는 동네 한 바퀴를 걸으면, 걷기 목표에도 무난히 달성하니 거의 매일 삼관왕에 등극합니다. 게다가 아직 목표에 미달하면 좀 더 열심히 하라고 격려도 해주고, 목표에 도달하면 축포도 터트려주니 좋은 세상입니다. [사진제공 정근두 목사]
Today, I would like to share the story behind our indoor bicycle (DVic). Some dear people who love us came all the way up to Goyang, where we were living at the time, with their whole family bringing along an indoor bicycle trainer. It must have been about four years ago. Back then, planning to assemble an indoor bike for exercise, I bought a second-hand bicycle from the local Karrot Market for 30,000 KRW. But putting off the assembly day after day, a few years slipped by, and I eventually brought it all the way back down when we moved back to Ulsan.
In the end, the very person who had carried it up to Goyang visited our home in Ulsan and personally assembled it for me. Right in the middle of assembling it, he realized that the worn-out rear tire needed to be replaced and went out to a bicycle shop in town. There, he managed to purchase a brand-new indoor training wheel that someone else had ordered three months ago and never picked up. Unlike ordinary bicycle tires, this specialized indoor wheel produces no rubber dust, so it felt truly like receiving a gift prepared beforehand by God.
The DVic indoor trainer is a brand known especially among home-workout enthusiasts who value cost-effectiveness and spatial efficiency. In particular, many of its models highlight features that allow you to exercise without boredom by linking with games or dedicated apps. Connecting via dedicated sensors or Bluetooth to workout game apps on a smartphone or tablet, you can ride alongside virtual avatars on the screen and enjoy an engaging workout. Furthermore, it employs a low-noise magnetic resistance system, meaning there is virtually no worry about floor-to-floor noise between apartments. Consequently, it can be used quietly even late at night or early in the morning. With resistance levels usually adjustable from 8 up to 14 stages, one can freely tailor workouts from light aerobics to high-intensity muscle conditioning. (The information in this paragraph was provided by Gemini.)
Being something of an early adopter, there was no way I wouldn't try turning on my desktop, linking it to the workout game app, and riding alongside the virtual characters on screen. However, for a 77-year-old elder (by Korean age)—and only about four months after undergoing surgery for a fractured left femur—it was physically quite daunting in the first place. Moreover, shaped by the competitive drive of someone educated in my generation, whenever an avatar on screen turned out to be a rider from across the seas, I found myself instinctively trying to catch up at all costs, inevitably pushing myself too hard.
So I changed my approach: while cycling, I tried listening to the freely available sermon audio files of Dr. Martyn Lloyd-Jones (MLJ Trust). Yet, killing two birds with one stone, or trying to catch two hares at once on one's own, was not as simple as it sounded. I ended up letting both birds fly away and losing both hares altogether.
Thus, I eventually moved the bicycle from the study to the living room. Now, facing the large TV screen, I turn on CBS's Make Us New (Sae-rop-ge Ha-so-seo) and start the indoor cycling workout on my wrist's Samsung Health watch; after a few seconds, a 45-minute program begins. Since an abridged episode of Make Us New usually lasts around 42 minutes, it fits quite comfortably.
For the ride, alternating every five minutes—three minutes fast, two minutes slow—burns about 220 kcal of energy. The Samsung Health app on my watch is set for daily goals of 1) a baseline of 6,000 steps, 2) 90 minutes of active time, and 3) 500 kcal of active calories. By cycling after meals in the morning and evening, and taking a stroll around the neighborhood after lunch, I smoothly achieve my step count as well, wearing the 'triple crown' almost every day. What's more, it encourages me to push a little harder when I fall short, and bursts into celebratory fireworks when I reach the goal—what a wonderful world we live in. [Photo provided by Rev.

Vandag wil ek graag die verhaal agter ons binnenshuise oefenfiets (DVic) deel. Mense wat ons liefhet, het destyds met hul hele gesin 'n binnenshuise fietstoestel opgebring na Goyang, waar ons gewoon het. Dit was waarskynlik sowat vier jaar gelede. Destyds het ek, met die doel om die oefenfiets aanmekaar te sit en te oefen, 'n tweedehandse fiets op die plaaslike Karrot-mark vir 30 000 KRW gekoop. Maar aangesien ek die aanmekaarsit daarvan van dag tot dag uitgestel het, het 'n paar jaar verbygegaan, en toe ons uiteindelik weer terugtrek na Ulsan, het ek dit saamgebring ondertoe.
Uiteindelik het presies dieselfde persoon wat dit destyds na Goyang gebring het, by ons huis in Ulsan gekom om dit self te monteer. Midde-in die montering het hy besef dat die erg verslete agterwiel vervang moes word en het na 'n fietswinkel in die stad gegaan. Daar het hy op 'n splinternuwe binnenshuise oefenwiel afgekom wat iemand drie maande vantevore bestel en nooit kom haal het nie, en dit dadelik gekoop. Anders as gewone fietswiele laat hierdie spesiale binnenshuise wiel geen stof agter nie—dit het waarlik gevoel soos 'n geskenk wat die Here vooraf vir ons voorberei het.
Die DVic-oefenfiets is 'n handelsmerk wat veral gewild is onder tuisoefen-entoesiaste wat waarde vir geld en spasiedoeltreffendheid waardeer. Baie van hul modelle lê klem op funksies wat oefening aangenaam en interessant maak deur integrasie met speletjies of spesiale toepassings. Deur middel van toegewyde sensors of Bluetooth kan dit aan fiksheidsspeletjies op 'n slimfoon of tablet koppel, sodat 'n mens saam met virtuele karakters op die skerm kan ry en met vreugde kan oefen. Boonop maak dit gebruik van 'n stil magnetiese weerstandstelsel, wat beteken dat daar feitlik geen kommer oor vloer-tot-vloer-geraas in 'n woonstel is nie. Gevolglik kan dit selfs laatnag of vroegoggend rustig gebruik word. Die weerstand kan gewoonlik van 8 tot soveel as 14 vlakke verstel word, sodat 'n mens alles van ligte aërobiese oefening tot strawwe kragoefening kan kies. (Die inligting in hierdie paragraaf is verskaf deur Gemini.)
Aangesien ek nog altyd 'n vroeë aannemer van tegnologie was, kon ek dit natuurlik nie laat om my rekenaar aan te skakel, die fiksheidstoep te koppel en saam met die karakters op die skerm te begin trap nie. Maar vir 'n 77-jarige senior burger (volgens die Koreaanse telwyse)—en dit boonop skaars vier maande ná 'n heupoperasie weens 'n gebreekte linkerdydbeen—was dit fisies van meet af aan baie veeleisend. En soos dit gaan met iemand van my geslag wat altyd geleer is om hard te kompeteer, sodra die karakter op die skerm iemand van oorkant die see was, wou ek hom ten alle koste verbysteek; dit was dus vanselfsprekend dat ek my liggaam sou oorreken.
Daarom het ek my benadering verander: terwyl ek getrap het, het ek na die gratis beskikbare preke van dr. Martyn Lloyd-Jones (MLJ Trust) begin luister. Maar om twee vlieë met een klap te slaan, of om twee hase gelyk te probeer vang, was nie so maklik soos wat 'n mens sou dink nie. Op die ou end het albei voëls weggevlieg en albei hase het skoonskip weggekom.
Uiteindelik het ek die fiets uit die studeerkamer na die sitkamer verskuif. Voor die groot TV-skerm kyk ek nou na CBS se Maak Ons Nuut (Sae-rop-ge Ha-so-seo), aktiveer die binnenshuise fietsry-opsie op my Samsung Health-horlosie, en na 'n paar sekondes begin die program van 45 minute. Aangesien 'n verkorte uitsending van Maak Ons Nuut gewoonlik sowat 42 minute duur, pas dit my net mooi.
Wanneer ek ry, wissel ek elke vyf minute af—drie minute vinnig, twee minute stadig—en verbrand so ongeveer 220 kcal se energie. My Samsung Health-horlosie is gestel op 1) 'n daaglikse doelwit van 6 000 treë, 2) 90 minute se aktiewe tyd, en 3) 500 kcal se aktiewe kalorieë. As ek soggens en saans ná ete fietsry, en boonop ná middagete 'n entjie in die buurt gaan stap, behaal ek my mikpunt vir treë met gemak en verower ek byna elke dag die 'driekuns'. Boonop moedig dit my aan om 'n bietjie harder te probeer as ek nog agter is, en skiet vuurwerk af wanneer ek die doel bereik—wat 'n wonderlike wêreld waarin ons leef. [Foto verskaf deur ds.
