Frequently Asked Questions
1. How quickly will I see results?
Results from online personal training, whether for fat loss or muscle gain, are highly individual and depend on several factors including your starting point, consistency with the program, adherence to nutritional guidance, and individual body response. A practical and systematic approach, like Zack Keen’s coaching, focuses on sustainable progress rather than rapid, unrealistic changes. Generally, clients can expect to start noticing positive changes in their body composition, energy levels, and strength within 4-6 weeks, with more significant transformations occurring over 12 weeks and beyond. Consistency and commitment to the systematic plan are key determinants of your progress.
2. What if I miss a weigh-in?
Missing an occasional weigh-in is understandable, especially in an online coaching model that values practical solutions. While consistent data tracking is important for monitoring progress and making informed adjustments to your program, a single missed weigh-in will not derail your entire journey. If you miss one, simply resume your weigh-ins at the next scheduled time. The systematic approach to tracking at Chasing Ants Fitness considers trends over time rather than isolated data points, so the overall trajectory of your progress remains clear even with a minor disruption. Communicate any challenges you face, and Zack can provide guidance on how to best continue your tracking and program adherence.
3. Do I need special equipment?
No, you do not necessarily need special or extensive equipment to begin online personal training with Zack Keen. The systematic solutions provided are designed to be adaptable to various environments and equipment availability. Initially, many effective fat loss and muscle-building exercises can be performed with minimal equipment, such as bodyweight, resistance bands, or a few dumbbells. As you progress, if specific equipment could enhance your results or if you gain access to a gym, your program can be adjusted accordingly. Zack works to create practical training plans that leverage whatever resources you have available to ensure you can consistently follow the program and achieve your goals.
