The participants will receive HF treatment as prescribed by cardiologists based on clinical guidelines. If participants have any additional medical conditions, their existing medications or treatments should continue. The prescribed medications should remain the same throughout the trial, with dosage adjustments only made if adverse events occur. The participants are also asked to maintain their usual physical activity, exercise routines, and dietary habits, without making changes outside of the study intervention. Researchers will contact incorrectly by phone weekly.

The participants will receive HF treatment as prescribed by cardiologists. If participants have any additional medical conditions, their existing medications or treatments should continue. They are also asked to maintain their usual physical activity, exercise routines, and dietary habits, without making changes outside of the study intervention. At the beginning, patients participating in resistance training should complete a pretest of one-repetition maximum (1-RM) to assess muscle strength, which will be used by a professional physical therapist to develop an individualized prescription. The specific movements are as follows: (1) leg press and (2) calf raise by Proxomed Compass 540 (Germany); (3) leg curl, (4) chest press, (5) push up, (6) seated row by HUR machine (US). During the 8 weeks, subjects will train 3 non-consecutive days/week with intensity 30%1-RM to 60% 1-RM, 3 sets/one excercise with 8-12 repetitions.

The change of muscle strength will be evaluated using handgrip strength, measured in kilograms. Each hand will be tested twice with a Jamar Hydraulic Hand Dynamometer (USA), and the highest value will be recorded.

The five-times sit-to-stand test is timed in seconds. Participants will sit in a chair without armrests, ensuring their back and lower legs are straight, with their arms crossed over their chest. They will then stand up and sit down as quickly as possible. The time is recorded using a stopwatch, beginning when the participants stand for the first time and ending when they sit down for the fifth time.
