Sables head coach Peter de Villiers conducted the afternoon session at RFUEA with the boys in white looking ready for the clash that will double up as 2019 World Cup qualifiers.
Zimbabwe arrived in Nairobi on Wednesday afternoon while Kenya Simbas returned on Monday morning after last weekend's win over Morocco in Casablanca.
Sables assistant coach Brendan Dawson was optimistic after Friday's run.
"Our team is fully fit we have no injuries at the moment we are very happy with our preparation and we are ready for Saturday"
As Zimbabwe started the Africa Gold Cup with a 23-23 draw against Morocco, Kenya picked a 24-28 win against Morocco to ensure a perfect start to the campaign.
"Kenya are aggressive and active in the field. They run the ball really wide; it's the way Kenya always play and we expect a high tempo game"
"The Kenya Simbas coach has been involved for a very short period of time, the amount of changes he can bring in am not very sure but it's the same Kenya, quite competitive side, big men who have rugby sevens influence so we expect the side we've had in the last few years."
Brandon was in-charge of the Zimbabwean side that beat Kenya Simbas in 2012 in Nairobi to win the Africa Gold Cup but says the World Cup picture does not add any pressure to them.
"It's exactly the same, we want to qualify for the World Cup pressure is on us(Africa), the standards in the rest World is improving day by day so we need to keep up with the modern pressure and pace of the game. Yes, pressure is here; let's say a bit of it but we want to qualify for the World Cup like everyone else."
Zimbabwe named the squad to play Kenya on Friday morning with prop Denford Mutamangira set to captain the side.
Of the 25 Zimbabwe players who traveled to Nairobi, only Lucky Sithole and Ziyanda Khupe do not make the match-day 23 named byPeter de Villiers.
Kenya Simbas head coach Ian Snook said his squad was looking good ahead of the match although he insisted on focusing on line-outs and breakdowns.
"Obviously we've watched video of their game against Morocco we realize there will be a big test. It will be difficult."
"We are looking to improve on line-outs and set-pieces also a little bit of scrummaging. We've been working on that. Otherwise the mood is positive and we are ready to go on Saturday afternoon."
