Both a recumbent exercise bike and a rowing machine are effective for conditioning and cardiovascular training, but the best choice depends on individual preferences and fitness goals. A recumbent exercise bike is gentler on the joints and may be more comfortable for those with back issues, making it a good option for low-impact workouts. On the other hand, a rowing machine provides a full-body workout, engaging multiple muscle groups simultaneously and offering a higher calorie burn. Ultimately, the best device for conditioning and cardiovascular training will be the one that you enjoy using consistently and fits your specific fitness needs. **

I recommend incorporating a combination of cardiovascular exercise, strength training, and flexibility exercises into your fitness routine for overall health and fitness benefits. Cardiovascular exercises like running, cycling, or swimming help improve heart health and burn calories.

It's also important to consider factors such as stress, sleep, and recovery, as these can impact your body's ability to adapt and improve fitness levels. Lastly, underlying health conditions or genetic factors could also contribute to poor fitness despite regular exercise. Consulting with a fitness professional or healthcare provider can help identify the specific factors contributing to your poor fitness and develop a plan to address them. **
