In addition to the HIIT sessions, it’s always a good idea to go for a 30–60-minute walk as many days per week as you can. I recommend getting a minimum of 10,000 steps every day. Use a phone app to track them. If you’re into jogging, swimming, hiking, or some other form of long-duration, fairly low-intensity cardio, that is fine to do as well, and as often as you like.
How do I know if my weights are heavy enough? Check your form. This workout involves many repetitions of the same exercise and you will know you are using the correct weight if your form stays consistent between the first part of a repetition set and the end. For example, a row from plank should look the same on repetition number 10 as it does in repetition number two, even if the effort is much greater. If your form is wobbly by the end, drop down the weight amount until you’re able to find consistency. Don’t forget that working with weights is not an all-or-nothing proposition. Your body also provides resistance. Try our 9-Minute Strength Workout for a weight-free option.
Want to know one of the top reasons runners end up hurt? Look at your backside. Underutilized gluteal muscles are to blame for a large percentage of injuries, says Nirav Pandya, M.D., assistant professor of orthopedic surgery at the University of California San Francisco Medical Center. And it’s a weakness that often occurs because runners are hyperfocused on building strong quads and hamstrings.
It has been argued that purposely overtraining for a brief period can be beneficial. One article published by Muscle & Fitness magazine stated that you can "Overtrain for Big Gains". It suggested that if one is planning a restful holiday and does not wish to inhibit their bodybuilding lifestyle too much, they should overtrain before taking the holiday, so the body can recuperate and grow during the prolonged rest period. Overtraining can be used advantageously, as when a bodybuilder is purposely overtrained for a brief period of time to super compensate during a regeneration phase. These are known as "shock micro-cycles" and were a key training technique used by Soviet athletes.
