Is combined training better for fitness if I only workout 3 days a week?

As a personal trainer, I'd say combining both types of training is a solid approach for most people, especially if you're limited to 3 days a week. Splitting your sessions to include both cardio and resistance training can maximize your time. For example, you can do a full-body resistance workout followed by 20-30 minutes of cardio. This plan not only improves cardiovascular health but also builds muscle, catering to different fitness goals at once. Just make sure you're allowing for adequate rest between high-intensity sessions to avoid overtraining.

I think it's a good idea to mix them if you're aiming for general fitness. Based on what I've read, combining workouts can hit both endurance and strength, giving you more bang for your buck. However, it's important to watch out for burnout. With only 3 days, make sure you're not pushing too hard back-to-back. Recovery is just as important, so consider adding a rest or lighter activity day if you're feeling exhausted. And always keep hydrated and fueled for those workout days.
