Week 3 - Strength training begins
Now that you are used to the grind, now is the time to put your practise to the test. Start building your strength with some compound lifts. The workout is distributed into three days to give muscles time to recover.
- Upper body
- Lower body
- Full body
Week 4 - Core and Endurance
Having a strong core means having great balance, posture, and strength to lift heavy loads. So, how do you achieve that? Adding exercises that strengthen your midsection and help you hold difficult positions during a workout. Exercises like,
- Plank (hold for 20-30 seconds)
- Hanging knee raises (2-3 sets of 6-10 reps)
- Stability ball rollout (2-3 sets of 8-12 reps)
Try adding some Low-intensity Steady-State (LISS) cardio, like an incline treadmill or cycling, to boost endurance without feeling too fatigued.
Week 5 - Increasing intensity
Now is the time for a progressive load, i.e., increasing the intensity of your workout. Start small and progress gradually. Do not rush or strain your joints. You can start by increasing reps, using heavier weights, performing an extra set, or slowing the tempo for increased tension.
Week 6 - Momentum building
Week 6 is all about slowing things down. Choose two or three major exercises, like squats, deadlifts, or presses, and perform them with a weight you are comfortable with.
- Pause for a few seconds before coming up while doing squats
- Lower the weight further while counting to four during lifts.
- Pull the weight towards your torso and push it back slowly.
Week 7 - Power phase
This week, you need to add more power to your workout. You can do this by adding some explosive exercises. According to the National Academy of Sports Medicine, explosive workouts help build muscle power and strength.
- Explosive exercises
- Strength Workout
Pair explosive exercises with some strength exercises to train your body to sustain itself under heavy load and switch more quickly.
- Back squats (5 sets of 5 reps)
- Box jumps (3-5 reps)
- Battle ropes (20-30 seconds)
Week 8 - Recovery
After a long period of intense training, your body starts to feel fatigued. To battle that, you need a week of recovery. In week 8, you will reduce the intensity of your workout so that your muscles, nervous system, and joints can recover.
Reduce your reps, reduce weights, and sets. The goal is to perform less than your capacity. Just keep on focusing on mobility.
Week 9 - Back to the grind
After a week of rest and recuperation, you are ready to get back to your routine. So, you rebuild your strength by slowly increasing intensity. Any area that needs an extra push can be toned by adding an accessory exercise to the main one.
Week 10 - Enhance your technique
Choose any exercise you have been doing since the beginning that you are confident in performing, e.g., squats or presses. Now try doing it with a weight attached. Be sure to check your balance in every rep and notice your core engaging naturally.
If you feel fine, increase the weight or a rep, but do not strain yourself.
Week 11 - Performance test
Week 11 is a time for testing everything. You test your strength, endurance, and power in a controlled environment to measure improvement. Carry on with your original routine, just add one intense piece that will test your abilities.
It can be a shorter rest period or extra reps. Simply adjust your weights to feel the rush of the movement.
Week 12 - Retest and plan ahead
Retest everything you learned in week 11 and compare your form, the weights, and plan for the future. Track your progress, even the small ones. And see which pattern benefited you the most, and then stick with it.
