Olsen has written academic books, fiction, philosophical books, children books, poetry, film manuscripts and numerous articles. He has produced CDs, directed documentaries, sung in opera, operetta and musical, composed music for films, performed in art exhibitions and participated in more than 100 TV and film productions as a stuntman, stunt coordinator, director or actor.

Olsen is the son of pictorial artist and writer Ib Spang Olsen and painter Nulle Øigaard and older brother of film director Lasse Spang Olsen. He is a Postgraduate from Aurehøj Gymnasium (1981) and holds a MA in Musicology and Classic History from University of Copenhagen and Royal Holloway and Bedford New College (University of London) (UK) (1982–2007).

Besides his Musicology, Olsen has received musical training in classical and jazz guitar, piano, singing, composition and direction. He has sung in several choirs and vocal groups and played in the bands Aurehøj Stompers, The Great Pretenders and RHBNC Jazz-band. Parallel to that he has composed music – such as children's songs, meditation music and film music.
Olsen was raised in a creative environment where it was natural to learn the classical art forms. Olsen received private education from his parents and different artists in the family circle, including Hedvig Malmstroem and Erik Lynge. Olsen's debut as an artist was in 1983 and shortly after that, he created Gallery MM in collaboration with attorney Martin von Haller Grønbæk. The gallery was dissolved in 1986. During 2008 Olsen resumed painting again and established in 2010 Eventgalleriet® (The Event Gallery) together with pictorial artist Barbara Kofoed.
Olsen is privately trained in stunt in US (1989 and 1990) by Eddie Stacie, Paul Stader, Gene LeBell and Benny Urquedes among others. In 1983 Olsen founded together with his brother Denmark's first stunt school, which today still stands as the world's only stunt school with a consecutive education. The education would last up to ten years and at the same time, the Stunt School initiated the Danish stunt industry. Most Scandinavian stuntmen have received tuition at the Stunt School. Olsen closed down the school in 1997 after 15 years. As a stuntman and / or actor, Martin Spang Olsen has appeared in more than 100 theater, film and TV productions since 1983.
Olsen holds several black belts and he has worked extensively with various forms of fight, from historical Western weapons forms to a wide range of oriental fighting styles since 1974. In 2005 he established Nordsjaellands Gong Fu Academi (NGFA) (North Sealand Gong Fu Academy), at which he is currently president and chief instructor. Olsen is trained in 19 different fighting styles in countries such as UK, US and China.
In 2012 Martin Spang Olsen founded The Sensoric Training Institute based in Copenhagen, Denmark.
In 1996 he founded the system Sang, Dans og Slagsmal (Song, Dance and Fighting) (SDS), an educational system designed to develop children's creative potential and along with this, the concept of The New School. At The New School, children are taught primarily creative, sensuous and physical disciplines for the initial 6 years in order to form the basis of their intellectual development. After this periode, traditional school subjects will be introduced and learned in a much faster pace – due to their initial training (traditional subjects, such as math, language, etc. have been available all along, but scheduled in the afternoon and on a voluntary basis). By request of the Ministry of Education, Olsen created the system Oeration Udadvendt Energi (Operation Outgoing Energy) (OUE) in 1999 (in its nature similar to SDS, but more addressed to children with psycho-social problems). In SDS, training works its way from the students' inner potentials (i.e. from inside out), and OUE works with the students immediate state of mind (from outside and in). SDS is described in the book Sang, Dans og Slagsmal, L & R Fakta, Cph, 1998).
Olsen has been consulting, lecturing and/or teaching at most Danish educational institutions and has acted as a consultant for the corporate world since 1985. In 2006 he developed the concept of Krop & Kontor (Body & Office) in collaboration with Ministry of Health. The system is applying to office jobs and is meant for improve job contentment, zest, and health. Projects are conducted in co-operation with MS Mads Andreasen.
Since 1985, Olsen held regular lectures on a wide range of topics, such as pedagogy, creativity, physical movement, health, religion history, etc. Olsen's lectures are typically based on a holistic concept of the world, in which a sophisticated complexity and interaction is paramount.
Olsen is the founder of the organizations: Olsen Productions (a merge of Olsen Music, Olsen Graphic, and Olsen Stunt Team), SDS (Sang, Dans og Slagsmål (Song, Dance and Fighting)) (1996)); OUE (Operation Udadvendt Energi (Operation Extrovert Energy)) (1999)); NGFA (Nordsjællands Gong Fu Akademi (Gong Fu Academy of North Sealand)) (2005 ): Reverse The Continents (2008); Kvalitativ Bevægelse (Qualitative Movement) (2008); and he is co-founder of a number of other organizations, including the K-Group (2002), NSFS (Nordic Stage fight Society) (1995); CFKH (Centre for Creative Energy) (2003), WACIMA (Worldwide Association for Chinese Internal Martial Arts ) (2004), Dionysos® (2007); Krop & Kontor (Body & Office) (2008)
