Both! I would have them do strength training and cardio. You could also have them do a lot of circuit training with the resistance exercises so they are getting cardio at the same time. I would include a lot of HIIT training with the type of cardio that they enjoy. Last but not least if they want to lose weight have them consult a dietitian as 80% of the workout is in the kitchen. Good luck!

Strength training vs. cardio: who wins?
I would say that strength training is more effective in the long run*.
Cardio only allows high calorie expenditure during the activity. Resistance training involves a certain level of calorie expenditure after the activity ends as the body repairs itself.
Intervals can burn more calories than steady state cardio BUT do you want to use intervals with a beginner or someone who thinks cardio is their Kryptonite?
In cardio’s defense, someone can train to the point where intervals are effective but the adaptation could take a while and may turn people off.
Weights can be modified so that beginners develop form.
*This does not mean that cardio doesn’t work! Cardio can assist in weight loss but weights have a certain advantage.
Plenty of great advice already on this thread. Most answers aren’t black and white. If I had to have a client do only one of these types of training, it would have to be resistance training. As people age, their muscle mass and strength constantly decreasing, albeit at different rates. Strength training will help you avoid decreases in lean mass, as well as burning calories at the same time.
I’ve had great success personally by strength training 2-3 days per week and just walking on off days. As many people said before, diet is the most important factor in losing weight. Strength training is important for maintaining muscle mass and improving function. Cardiovascular training can be important for heart health and functional endurance. I know that this is a very simplistic way of looking at things and that strength training can be beneficial in cardiovascular health as well, but that is just how I justify each method of training.
