Spreading a few exercises here and there throughout the day is never a bad thing. Matter of fact, it's probably better for many than getting one big workout in that takes up some time. Some do like getting in that hour long or so workout either before or after work which is awesome and I applaud you for making that effort, if you enjoy it and it's meaningful to you, keep at it. There are other options though if you need it to save yourself some time.
Doing a few moves or holds over the course of the day can help you stay strong and fresh for what is thrown at you and getting the most out of it in little bits of time. Even certain exercises that seem basic can be very challenging when done right. One of my favorite exercises believe it or not I like to do for a couple minutes a day along with the other things I do is doing Push-ups either on my fists, palms or using my handles and I would hold at the top for as long as 30 seconds, then go down to about mid point and hold that for 30 seconds, come back up and hold for 15 seconds, mid point for 15 and repeat that 15/15 one more time for a total of 2 minutes without a rest. It's tough as hell but it gets the job done. Picked up that version of push-ups on youtube but do different variations instead of just one (variety you know).
Combining dynamic and isometrics is a great way to keep your strength and condition up and keep things flowing. Do a wall sit for a minute or go bear crawl for 30 seconds to a minute, these will add up as the day progresses and it'll feel like you're getting more done than you thought. Micro Workouts are a key ingredient to successful training and it pits you into a style that can be creative using simple moves and holds. Got a way to do Suspension Training? You can do some assisted pull-ups to build strength and muscle in your back or do rows as you advance. Washing dishes? Every few plates cleaned or so, press down on the countertop for 10-12 seconds and tighten the core muscles. Want to work the legs a bit, if you're going up a couple stairs or so, take a step and press hard with the front leg for 5-10 seconds each leg to build strength in the quads and knees. Sometimes the littlest things can create the biggest impact.
A great exercise for the lower body is the Amosov Squats which I picked up from Steve Maxwell in the case of doing assisted type squats using a counter space, a door or using a Suspension Strap. Go down as low as you feel comfortable and come back up within control. As you get better, get down a little further and slowly build up speed. This builds great strength in the legs and conditions the entire lower body. Some do this to get the blood flowing as a warm up, others for conditioning purposes and to help with building strength in the knees if they can't do squats unassisted yet.
Build a foundation and utilize your exercises the best way you can. Don't be afraid to experiment with something and don't think for a second that simple exercises are too easy, when you utilize the right tension and timing, they can be crazy tough to do but yet be as effective if you were doing a long workout. A few seconds can feel like an eternity at times. Making even 5 reps feel like 50-100 is a killer way to train. Have fun with them and keep being amazingly awesome.
