Ethan,
Sorry so long to reply... work has been crazy lately. Okay, here's the home workout routine that I started with. Remember... I was obese, completely out of shape (zero fitness level) and had to workout at home due to various life conflicts. I want to introduce you to The LCAB Matrix. (pronounced "L", as in the letter "L" and "cab" as in taxi cab.) The LCAB Matrix is a super simple way to remember how to do a full body workout. Here's what LCAB stands for:
L - legs
C - chest
A - abs (core)
B - back
The way it works is you start with Legs, then Chest, then Abs then Back... like this L > C > A > B. What is also going on with this LCAB setup is the sequence itself is strategic in that it allows one muscle group to rest while working another. For instance, after the legs, you move on to the chest (letting the legs rest). After the chest (which engages the arms) instead of going straight to the back exercises, you'll instead do abs (so you're letting the arms rest) before working the back which engages the arms, etc. The workout structure is simple: you just need to pick one (1) exercise for each muscle group.
Here's An Example of an LCAB Workout Using Just Bodyweight Exercises
Set 1
L - Prisoner Squat (10 reps)
C - Pushups (10 reps)
A - Plank (60 seconds hold)
B - Pullups (as many as you can)
Time: 3 min
Rest: 1 min
Set 1: 4 minutes total
Then you repeat for a total of 4 sets (about 16 minutes total).
Notes:
1. Rest only 15 seconds between exercises.
2. Rest only 60 seconds between sets.
3. Controlling rest time between exercises and sets is the way to keep the intensity up.
4. If necessary, take 4 minutes to complete the exercises, with 1 minute added for rest, for a total time per set of 5 minutes (4 sets = 20 minutes)
5. For Pullups: I personally could not do a single full pullup when I started. I had to start with dumbbell rows and slowly build upper-body strength (arms, lats, etc.)
6. Number of reps is for illustration purposes only. Generally speaking, rep range is typically in the 8-12 range for conditioning and non-bulking purposes. (For bulking/gaining, heavier weights and 5-8 reps is typically used to build more dense muscle.) To get started, keep things at 10 or so reps (or less if you cannot do 10).
Here's An Example of an LCAB Workout Using Dumbbell Weight Exercises
Set 1
L - Dumbbell Squat (10 reps)
C - Dumbbell Bench Press (10 reps)
A - Plank (60 seconds hold)*
B - Dumbbell Rows (10 reps)
Rest
Same notes as above.
Warm-up and Cool-down
Before every single workout, I'll do a 3 minute warm up that consists of just bodyweight exercises. Here's mine:
Jumping Jacks - 50 reps
L - Prisoner Squats (10 reps)
C - Pushups (10 reps)
A - Isolated Ab Curls (10 reps each side)
B - Dumbbell Rows (8 reps each side, lighter weight than used in workout)
Cool-down is usually a 5-minute slow walk.
* Worth mentioning that when starting to work out again, everything will feel awkward. Just push through that initial awkwardness and finish a workout. Every day it will get easier, and you'll get in the flow.
* You can do this 20 min workout routine every day if you want to, as long as you can do them safely and with proper form. You must avoid injury at all costs. Do all the movements nice, steady and slow... with control. No jerky, explosive movements. Even the bodyweight exercises. Once you start increasing the weights and intensity, you might want to do the workouts 3 times a week on non-consecutive days, because the increase weight and load on the body might warant more rest between workouts. If necessary, you can even start with 3 workouts a week too (this would be a minimum) along with the clean diet.
* It's not a bad idea (if you have access to a local personal trainer) to just hire them for one session to guide you through the proper form on these movements too (if you need it).
Let me know if you have any questions or if I left something out.
