PHIIT Strength has levels 1 and 2 whereas PHIIT Strength Pro has levels 3 and 4. This is an increase in difficulty of the program and the weights used should be challenging but appropriate for you!
Following feedback from our members in our Facebook group who said they wanted a program that had focus on the triceps and arms, weighted core movements, back strengthening and weighted leg movements, Kari has created this program for YOU!
