Logo Design

Information for the business: We are "Free Athlete" company launching an app that will provide exercises for people willing to train body weight only exercises. See "Freeletics" as a comparison.
Industry: Sports and Fitness
Brand name/slogan in logo: Goliaz
Ideas for the visual style: We like bold, smooth visuals and prefer abstract to character. Goliaz is the brand name and is based on the "Goliath" character from Marvel Universe comics, Goliath from "David & Goliath" and also on the Star of Goliath. We will be name the exercises after stars, constellations, planets and other items associated with the universe so if we can tie in space, planets, the universe or similar into the design that would be good. Goliath literally means "mammoth", "titan" or "colossus"
Things to avoid: Character images. More than 3 colours
Preferred colors: Black, white, gold, silver, yellow, red, purple, orange
Where the design will be used: Apple/Android App, T-Shirts and other apparel.
