CIYMS Tennis Coaching Program

Meet Our Head Coach

I’m Johnny Abosi and have been coaching tennis now for 15 and over years. I’ve played tennis all my life and am extremely passionate about the beautiful game.

Having represented Ghana, as a junior player, I have gone on to play for Ireland at senior level, taking part in the Four Nations Championships and also playing at the World Championships. I enjoy playing for Ulster regularly and have captained the Ulster Senior Interprovincial Team. As well as coaching and playing, I love competing at a high level.

As a coach, I work with players from all walks of life, and nothing gives me greater pleasure than to see them improve and the happiness that this brings people. I’m all about having fun on court but what gives me the greatest satisfaction is the hard work put in to improve every aspect of the game.

Coaching Qualifications: TI (Tennis Ireland), PTR (Professional Tennis Registry), RPT (Registered Professional de Tennis), MTI (Modern Tennis International)

Junior class descriptions:


This is aimed at 4-7 year olds. It’s played with a larger than normal red transition, low compression ball. This makes the ball easier to use for the younger children giving a much higher rate of success. The emphasis here is in fun and the learning of simple A,B,C’s agility, balance and coordination. Technical content is very basic and only at grass root and fundamental levels.

All red class last for 1hr.

This is a step up from a red ball class and aimed at children 8-9 years old. It uses a normal size low compression transition orange ball. This stops the ball bouncing to high for the children and assists them to develop their technical and tactical skills and allows them to rally and score. Coaching become more technical and various different grips are introduced e.g. eastern and semi western.

Orange ball classes are 1hr.

This is a progression from an orange ball class aimed at children from 10-11 years.  The ball used is normal sized and has a compression level between an orange ball and a normal standard tennis ball. Green class are play on a 3/4 sized tennis court and kids are encouraged to serve, rally, score and compete. All elements of tennis are introduced during lessons. Projection, reception, technique, body biomechanics and tactical awareness.

Green ball classes are 1.5hrs.

Orange ball classes are 1hr.

This is the progression from a green ball class. They are aimed at children from 10 years old to adult level. A standard tennis ball is used hence the bounce is higher so the children must be able to play a competent game of tennis with a green ball in order to progress on. All aspects of tennis or covered during a term of yellow ball classes. Techniques, tactics, biomechanics, fitness etc. The children are always encouraged to play, compete and score at this level.

All yellow ball classes are 1.5 hrs.
