If your dojo is closed... How are you keeping in shape?

Jogging when it's nice out, elliptical when it's not. Pushups, leg raises, stretches, kata.

I started to plan lessons for our beginners and I am working through them in my living room.

Kihon and kata are always an option. Kihon can be done on the spot and requires little space. Throw in some planking afterwards for a couple of seconds and then just lie there and relax.

If you gain weight, then you don't require all the energy you take in. With biking you are going to reduce your body flexibility over time because you do these small circular movements and the body gets used to it, so add flexibility training.

Ring Fit Adventure is the greatest thign that's ever happened to fitness since man learned to run

Running, walking, lifting weights, and (I should do a lot more) flexibility work. Also being mostly mindful about eating and drinking.

If you don't have a dojo to train at, use what you know and make due with what you can do. The 2/3rds triathlon is a good move. Biggest thing is to make sure you keep your diet clean, portions checked, and develop a routine that works for you.

I feel you on bodyweight training. What I did was just every other day worked a different muscle group with one or two bodyweight exercises, mixed with Karate and running.

Take it a step at a time and you'll get to where you want to be until stuff is open up again.

I'm trying to get leaner, so jogging and going to do some strength training(mixed dumbbells and bodyweight), also trying to better diet as well.

For me its kettlebells mainly and the routine is:

Static stretching

Dynamic stretching

Kata

Kettlebells

I try to do all exercises in hour and half.

Going for walks and doing curls bringing my food to my mouth (sorry, smart ass answer). Truthfully, I’m not either. I’ve gained the Covid 15-20, & it is frustrating.

I train about 2 hours 3-4 times a week. Junbi Undo, Hojo Undo, Kihon, Sanchin and other kata.

being honest just keeping going and making schedule of workout routines and practicing, you know practice makes perfect you know also trying other things and learning om body conditioning and building, running and stretching, ect

Round is a shape.

Seriously, though, my dojo is open in person and there are Zoom classes. That said, I've been threatening to get more into calisthenics/body weight exercises. I was training a few years back with a BJJ instructor who looked like a fitness model, and I asked if he worked out with kettle bells or something like that (they were very popular at the time). He said no, just body weight exercises. The obvious advantages are that you don't need any gear, so you can do them anywhere. There are a ton of YouTube vids, and I also recommend a book called You Are Your Own Gym.

For cardio I've used TABATA and jumping rope in the past - I might start doing either or both of those again.

Edit: Oh, duh, I just re-read your post and saw where you said you don't like bodyweight exercises. So ignore that.

I have set up a training area with eva mats in the garage and one mon wed fri we have zoom trainings from the head of our org and Tuesday and sat we have our local club virtual class. plus through out the week I do yoga and weight training.

i was training for a MT tournament, but it got cancelled.
but i also do exercise between rounds of competitive online games...though that's been kinda hit and miss lately lol
