2. Physically fit ascertained using Daniels' equation https://runsmartproject.com/calculator/, 5K time: ≤ 23.0 min, and/ or 10K time: ≤ 48.0 min These criteria will maximize the likelihood of including individuals with VO2max of at least 40 mL/kg/min.

2. Has a body mass index (BMI) between 18.5 and 32 kg/m2, inclusive

3. Willingness to engage in 10-weeks of intensive exercise training designed to improve aerobic capacity and endurance, muscle strength, power, and fatigability, anaerobic capacity, and body composition, and to reduce fatigue

4. Willing to not engage in additional exercise training if randomized to the progressive exercise group and willing to not change usual physical activity if assigned to the usual physical activity group

5. Is free from clinically significant medical problems as determined by the Investigator
