David Sisk Personal Training and Fitness Cork

David Sisk Fitness was founded in 2003 and is Cork’s premier personal training studio. After returning from the USA with a Master of Science in Sport Degree David believed that a niche existed for specialised expert personal training and nutrition advice in a high-end environment. That belief is even stronger today.

Some clients stay for 10 sessions and many clients have stayed for 10 years! We would like to think that with over 85,000 sessions completed that we have the knowledge, qualifications, and experience to help our valued clients achieve what they set out to.

David is so long in the area of exercise science, training and nutrition that the concept of the Internet hadn’t been conceived when he began his career. A love of exercise in a scientific sense began way back in 1990 for him. He completed a double honours degree in Psychology in UCD which included a thesis on key psychological effects of injuries on elite international athletes. After completing a Graduate Diploma in Entrepreneurial Studies in Smurfit Graduate Business School (UCD) he went to the USA to complete a MSc in Sport which included team and individual training. He began personal training people during that period while working in a financial institution in Cincinnati. After one too many summers of 90f degrees of wearing a shirt and tie – and working for people – he decided to ditch the suit. Along the way he has completed numerous certifications in training and nutrition, along with a certification in life coaching. His scientific knowledge and experience along with his psychology and coaching qualifications and training has provided him with the perfect tools to get you the results you seek in your personal training journey. He has surrounded himself with some of the best trainers in the business to form a great team that will do it’s best for you.

Our Personal Training Philosophies

We have certain philosophies that we stick by so we can be the best for you.  I have no doubt you will begin to see these philosophies in other personal training studios in the future; we’ve had them for over a decade:

  • We train you to your abilities and capabilities.  Our clients at David Sisk Fitness range in age from 70-15 years old with varying degrees of training experience (many have zero experience which is most common in Ireland). A large number of people who come to us have never trained before so we bring you through the phases step-by-step.
  • We train you through individually designed programmes based on the Optimum Performance Training™ (OPT™) model from the National Academy of Sports Medicine (USA)- not workouts.  Workouts are easy; you just do loads of different exercises in a period of time with no real structure.  You’ll benefit somewhat but workouts have no real goal, no real objective, no balance.
  • The personal programmes we bring you through are designed through analysis, re-assessments and science.  We reassess you frequently so you can progress correctly.
  • We don’t do fad diets- they don’t work in the long run. Exercise alone won’t get you where you want to be, you need nutrition.  We’ll give you a plan and we’ll teach you how to eat so when you go ‘out into the world’ you can maintain and continue what you have achieved with us.
  • We believe the environment you train in affects the way you train.  We offer a high quality personal training studio in an exclusive location.  If you prefer a warehouse in an industrial park with dark lighting then that’s great but it’s not the David Sisk Fitness way of personal training.  We are here to provide the best environment to focus on you.
  • We train you based on our own research sample size of the over 85,000 personal training sessions, our sports and nutrition qualifications and based on our experience of 13 years in business as Cork’s longest running personal training studio.

Frequently asked questions

Not everyone is suited to personal training at David Sisk Fitness. This is where the initial assessment comes in. Personal training at David Sisk Fitness is not just about the physical training. Believe it or not that is sometimes the easy part. Commitment, organization, willingness to make some changes, these all determine whether you are suited. These can all be worked on as the personal training.
No! If you eat salads all the time you will lose lean muscle, your metabolism will slow down, and you will probably end up putting on weight in the long term. Starvation is the BEST way to PUT ON weight. If you eat small salads all the time or starve yourself for long periods you will lose weight for a while but then as your metabolism slows your weight loss will slow. We put people on food plans that are healthy, tasty, and can be followed for life, not just for a few weeks.
It is physiologically IMPOSSIBLE for muscle to turn to fat. Both are completely different materials. Muscles simply shrink back to their original size. People tend to put on fat when they stop training because they continue to eat the same amounts of food as when they were training. If you’re not training you don’t need as many calories to get you through the day.
If you are a WOMAN you will NOT get big muscles. Women have very little testosterone compared to men so weight training will only get you lean and “toned”. The more lean muscle you have the more fat you will burn. If you are MAN, you will have to work very hard and eat strictly if you want to gain a large amount of muscle mass.
Well, its not easy, but we only design programs that are within your capabilities. We are demanding because we want you to focus on and reach your goals. Training is challenging BUT it should also be FUN! You can lose that weight fast but safely, you can and will lose that belly fat and you can be healthy if you follow our dedicated advice. We strongly suggest you ignore the fitness programs you see on tv where trainers are shouting at people. These trainers do this for 2 reasons : 1. it makes better tv 2. they are not very good at coaching so they motivate and communicate by shouting.
